Dear World of Tanks players!

Yesterday on radio Wargaming.fm there was a program called “Developer’s Hour”, during which the issue of implementing the “Sandbox” mode was discussed in detail. At what stage is this World of Tanks project now and will the server be launched soon for the bulk of players? About these and other questions right now: - We have already received first impressions, collected feedback, familiarized ourselves with it and sent it to development.

"Sandbox" World of Tanks

• - We won’t rush anywhere, when we understand what suits everyone, we’ll release them to the base when they’re ready.
• - Initially, there were two waves of invitations, those people whom we chose ourselves, this is our initiative, and the second - applications on the portal. The main criterion is the presence of a level ten tank.
• - Yes, in Sandbox There are players who don't have a ten on base, but they are very few.
• - Applications are reviewed constantly.
• - The second wave has already been launched.
• - There are no limits yet, but we must respect a certain number of people on the server.
• - Applications are considered on a first-come, first-served basis.
• - In the future we will change the recruitment criteria.
• - We didn’t have a task to kill or nerf this or that class, we had a task to make a different one, in general, balance.
• - It’s too early to talk about the processing of LBZ, now is the earliest stage of balancing. Of course, there will be changes if necessary.
• - Additionally, we will send questionnaires to participants Sandboxes.
• - We plan to test other features on this server, but now only balance.
• - Currently there is a limit of 3 Arts on each side on the test server (at the moment). The balancer tries to choose exactly this way.
• - The combination of tank destroyers and self-propelled guns will not go away; now tank destroyers will have a better equipment.
• - Now we are doing balance on 10 levels, for example, it will be possible to get to 6-7, but later.
• - Our main task for ST was as follows: In order for ST to stop punching TTs in the forehead from 400+ meters, we want to return to the role that was before.
• - The rebalance will affect the economy, but this will happen later, at the final stage + another bonus for tanking.
• - There are negative reviews regarding the stun sound (debuff), but all these sounds and icons are preliminary, they will still change more than once, especially the performance characteristics of tanks.
• - “Serbogolda” is disabled in the Sandbox in order to collect good feedback, but all changes to Sandbox we consider as potential.
• - Those who received invitations will not be kicked out.
• - When selecting applications, we do not look at age.
• - We are thinking about encouraging testers Sandboxes.
• - We are still experimenting with the stun time.

What is Sandbox?

“Sandbox” is a separate test server on which developers together with players will work on a new balance of World of Tanks vehicles.

How to get into the Sandbox?

To get started, submit your application by clicking on the button below. You will be taken to a special page where you will complete your application in a couple of steps.

What are the selection criteria?

Not everyone will have access to the test server. The criteria for selecting participants depend on the objectives of a particular testing stage, but the goal will remain the same - to invite players who are not indifferent to the fate of their favorite game and are interested in close cooperation.

How do I know if my application has been approved?

Tankers who have access to the test server will learn about this from several sources:

• A letter to the mailbox associated with the account.
• Notification in the game client.

We will need time to process applications and determine the number of invited test participants. It is planned that the first wave of invitations will fall at the end of May - beginning of June.

2. Details

Updated

“Sandbox” is a special server for testing prototypes of the new World of Tanks balance. Here we plan to test various balance options and choose the most suitable one that will solve the problems we need and will appeal to the players. The primary task is to set up a new balance of equipment for the “top” levels. First, testing will be carried out on Tier X vehicles and Tier VIII light tanks, then the approved solutions will be applied to lower levels of equipment.

We do not promise that the tested prototypes will be released on the main server in their current form. Their final implementation will depend on the information collected and analyzed.

Goals of the new balance of technology

• Increasing the role of armor in the game. Now the game value of such an important aspect of a tank as armor is significantly lower than that of mobility and combat power. We hope to increase the impact of armor in the game.
• Reducing the cost of mistakes in battle . We are going to reward players for active actions in battles. Increasing the role of armor will allow you to act actively, without fear of going to the Hangar at the first detection, because it will become much more difficult to penetrate a tank at a long distance. Risk is a noble thing, and the reward for it in battle should not be excessive.
• Reducing the risk of focused fire at long ranges. Increasing the role of armor increases the survivability of the tank at long distances, including under fire from several opponents. Collective control of directions and firing at an enemy tank when it is “exposed” will become less effective, since it will be more difficult to penetrate armor at a great distance.
• Reducing combat distance. Long-distance artillery duels should not be the main tool for achieving victory. Combat vehicles must fulfill the roles originally intended for them: “tanking,” pushing through directions, and much more.
• Increased variety in gameplay. If different types of vehicles have different roles and the ability to play them effectively, battles will become more diverse. By choosing a different class, you will choose new gameplay, new game problems and ways to solve them.
• Smooth increase in combat dynamics. Changing armor penetration with distance will encourage players to take more active actions in battle to achieve victory.

Major changes

To achieve the goals of the new balance in the Sandbox, several core game mechanics will be changed.

Distribution of shells in the aiming circle

To reduce the effective fire distance, the distribution of projectiles in the aiming circle will be changed so that the need to aim completely will increase. This will increase survivability under fire at long distances.

You can learn more about how projectiles are currently distributed in the information circle on the main game servers in

Reduced armor penetration of shells with distance

WITH increasing the distance b armor penetration will drop more noticeably - this is done to increase the role of tank armor in the game. It will become more difficult to fire at a greater distance, and in order to increase the likelihood of damaging an enemy tank, players will have to take more active actions: getting closer to the enemy or taking up positions to fire at their weak spots.

In addition, it will become more difficult to penetrate a tank at a long distance into the most protected frontal projection - thus, heavily armored vehicles will have more opportunities to push through directions.

Changes in the degree of decrease in armor penetration with distance will not affect close fire combat - the features of its conduct will remain the same.

Systematization of projectile damage

There are currently many more large-caliber guns in World of Tanks than there were in the initial stages of the game's development, and there is a need to recalculate the damage of guns. As part of the Sandbox, a new system for distributing one-time damage of various weapons will be tested. The system being tested should reduce the number of shots that deal critical damage and increase the value of the damage per minute metric compared to one-time projectile damage.

Change in vehicle maneuverability

Along with increasing the survivability and lifespan of a well-armored tank in battle, it was decided to add gaming capabilities for weakly armored but mobile vehicles. Class or role relationships between the rotation speeds of the chassis and turret will be determined. As a result, more maneuverable vehicles should be able to actively maneuver and “twist” slower, but better armored vehicles.

Role models for various types of equipment

At the moment, almost any class of equipment performs most game tasks equally well, with the exception of self-propelled guns and some light tanks. This situation reduces the variety of gameplay, because the effective actions taken by the player in battle are practically the same for most classes.

The gameplay changes listed above are intended to introduce a division of equipment into game roles. Based on expert assessment, 7 main game roles were identified, and through game parameters we emphasized the game functions that the machine should perform. Please note: role names are not finalized.

In general, among the system changes we can highlight a general change in the maneuverability of vehicles, due to which it became possible to identify some game roles, as well as a noticeable decrease in visibility indicators.

It is important to understand that the changes made are not final and will be changed repeatedly, both taking into account feedback from the gaming community participating in testing, and taking into account the analysis of statistical data.

Self-propelled gun class rebalance

As part of the rebalancing of self-propelled guns, it is planned to change their main task in battle. In the new role, self-propelled guns will be refocused on supporting allies by stunning enemy vehicles, and dealing damage for this class will fade into the background. In addition to changing its role in combat, the self-propelled gun class will receive several new features to increase efficiency and ease of use.

New features of self-propelled guns:

1. Explosive/shock wave, stun. Spreads along with the splash after the shell explodes. Tanks that fall within the radius of the blast wave temporarily suffer a deterioration in their performance characteristics. Damage dealt to stunned tanks is counted as damage dealt with your help.
2. Allied artillery marker — display of the approximate area on the map where the allied self-propelled guns are deployed. Appears when you press the “Attack” key (by default the T button), provided that the central crosshair marker is not on an enemy vehicle (in this case, an alert will appear about a possible attack on this tank). Allies will see a graphical display of an approximate circle on the mini-map and directly on the location, and a message will also be displayed indicating whether the self-propelled gun is charged. This is intended to improve team communication.
   
3. Alternative sight for self-propelled guns. The new sight changes the type of aiming on self-propelled guns, making it similar to sniper mode on other types of equipment and more convenient for the player.

The changes will also affect high-explosive shells: the amount of damage inflicted in most cases will be reduced, and the spread of fragments of high-explosive shells will increase (splash radius). We can say that self-propelled guns will switch from dealing damage to a specific player to dealing damage to clusters of enemy tanks.

Access to the test server may be terminated or limited at any time for failure to comply with the provisions of the User Agreement and.

In particular, according to clause 9.2 “Beta testing” of the User Agreement, “any information received by the User during beta testing is confidential and is not subject to disclosure.” Any distribution of information from the Sandbox server (live broadcasts, video reports, etc.) without the consent of Wargaming representatives is prohibited. You can agree on the publication of such materials in a special topic on the “Sandbox” server forum. Only those players who have access to testing can submit applications.

3. Answers to questions

Updated

Answers to player questions

Anton Pankov and Daniil Murazor Paraschin answer questions from Jove and players about the Sandbox server.

Why was the stabilization “cut” in the “Sandbox”, although the spread within the convergence circle had already increased?

Not all tanks had stabilization worse; on some vehicles it became better. The stabilization is made in such a way that a nearby player can easily hit the silhouette. I cannot say that it is ideal now, but this is precisely why we need to collect statistics, thanks to which the balance will improve. In addition to this, the maneuverability of the turret and hull was “nerfed” for all heavy tanks, now it has become possible to spin the “heavies” - this is all part of the new role-playing system and balance.

Do you plan to add new people to the Sandbox?

Of course, every week we try to add new players, and of absolutely all levels of play - not just extras. It’s summer time, and many of those we invited are not playing yet, but we believe that interest in the “Sandbox” will be high, because it’s up to those playing there that how everything will turn out depends.

The artillery's accuracy has become too good, is this not unnecessary?

Well, artillery can’t “one-shot” anyone anymore, so the decision was made to increase the accuracy so that it could be hit predictably. Stun is still a new mechanic, it was not in the game and this feature has not yet been configured. The ability to reduce the duration and strength of stun will be given. Yes, it is annoying, but you can calmly drive, push the direction and be sure that you will not suddenly be killed.

One of the new features we'll be testing is banning or restricting artillery from playing in a platoon.

What about the bonus for tanking?

It is being done little by little. At the moment when we were ready to release it, it was absolutely unrealistic, gave too much of a bonus, and it was impossible to do it correctly. This also includes a bonus for assisting from artillery - these are mechanics that will allow you to earn money without causing damage.

Why is the T110E3 120 mm?

Because we have too many tanks with very good “alpha”. There cannot be super armor and super “alpha”, but I don’t really like the T110E3, it will still be “upside down”. Keep in mind that in the new balance there will not be a large number of “ten” in one battle, and how can you fight against a “ten” with excellent armor and a gun on the “eight”?

Are you planning anything interesting in terms of maps?

We will also add some problematic cards to the Sandbox, we just want to figure out the performance characteristics for now, and then other changes will appear here.

Some of the problems with maps will be resolved on their own with the release of the new balance, because thanks to the new role model and artillery changes, players on old maps will behave differently.

Is stun the only feature the art will have?

Yes, there will be no smoke shells, illuminating shells, etc. We have discussed this more than once, and this will not happen precisely because if e-sportsmen can use it at the highest level, then an ordinary team will not be able to use it. Smoke will fly towards the allies and disturb them, “lights” will be thrown in the wrong place, or no one will shoot there, and in the end we will get a very toxic thing.

Why is it forbidden to stream “Sandbox”?

We are not ready to allow streams yet, because we are not ready to shout to the whole world that everything is fine, everything works great, the changes there are still very harsh, and broadcasts can scare many players who are not familiar with the Sandbox. This is a very important project for us, and in the future, of course, there will be both official and unofficial videos from there.

Nowadays, due to its large splash, art often deals more damage to allies than to enemies. Will you do something about this?

Damage to allies from art will lead to penalties, no one will be able to shoot at a bunch of allies to stun one player. But this system is still being developed. If artillery indicated that it was shooting at a certain point, and then an ally drove there, fining for this, of course, is wrong.

I read that the balance will be done for the “ten”, and then go down, but there was also an opinion that level VI and below will hardly change - is that so?

It is not true that there will be no changes at all, but there will be fewer changes at the lower levels. A role model is really more about high-level technology. The changes below will be made to make it comfortable to play at these levels, without such serious alterations.

Eight platoons are always at the bottom of the list, are you aware of this problem?

We know that this was done because now the balancer tries to determine platoons by platoons, and when it does not find a platoon of “eights”, it looks in “nines” and “tens”. We will try to fix this in the new balancer. We want to create a 30/30/30 system, where 30% of battles the player is at the top, 30% in the middle and 30% at the bottom.

Are there any plans to change the situation with +/-25%?

So far we think it's OK. There are no serious problems with this even in esports.

How long will it take you to test all this?

This activity is new and very risky for us. The team will work until the players who play in the Sandbox (and in the end all players will be added there) say that the game has become better, that they like the technology more. If it turns out that we tested and tested, but in the end the players say that the balance on the main server is not so bad and nothing needs to be changed, we will not release balance 2.0. But we hope that this will not happen.

Prohibited mods, “cheats” - what’s wrong with them?

Pankov :

Before the start of the football tournament, we banned and suspended a large number of people with “vango sight”. We found a way to identify them and punish them. We will continue to do so. We are creating a tool that will calculate all prohibited mods 100%; we are currently working very hard on this.

Are you planning to do anything on the Global Map to attract more people there?

We are planning, but our main priority is “random” and balance in “random”, first it, then everything else.

We consider them colleagues, not competitors. We really closely follow the development of these projects, but taking something from them and blindly copying it would be dishonest and wrong.

Personal combat missions?

We know that people want LBZs, we are thinking about how to make them favorably different from the current ones (we do not plan to turn off the current ones) and how to make sure that more people can implement them.

Light tanks are not very comfortable to play at the moment, what are you planning to do with them next? Besides dynamics and visibility?

The role of “light” will be returned to them, this is understandable, they will become the best scouts, but the problem is that LTs now largely do not cause damage, because LT-8s are difficult to play with “nines” and “tens” in the new balance. I won’t promise anything yet, we tested different options, and no one knows what will happen in the end.

Will the client be added to MacBook?

This is important for us, we encountered serious problems with the release of 9.15. And we are thinking about making a client for Mac ourselves, rather than using a third-party version.

Will you be adding new perks to Balance 2.0?

Of course, we will, while this is the concept stage, but we understand that the current “perks” are not enough.

The topic of “perks” has been raised many times, but first we want to make a balance for the role model, and then “perks” for the same roles.

What are you planning to do with the gold?

We want to reduce its toxicity. Our goal is to increase the lifespan of tanks, and there may be different options, all of this will be tested in the Sandbox.

Regarding setups and balance. Will you manually adjust the setups so that one team doesn’t have 7 tank destroyers and the other has none?

Very intensive work is currently underway on the balancer. Ideally, it will take all of these issues into account. What the balancer will do exactly is an equal number of tens, nines and eights in each of the teams.

Are the developers going to remove the “15 m from the bush” feature?

At the moment, this mechanic suits us. When we reach a more precise balance, we will see how this parameter fits into the new rules, but for now we do not plan to remove it.

Aren't you afraid that players will get confused by the role models?

Afraid. We will work to make this as clear as possible: information in the client, etc. We will switch to the role-playing model very gradually so that this causes as little discomfort as possible for the players. A role model is additional information to the player about what strengths and weaknesses his tank has, because classes are more of a historical concept, and heavy tanks often play like medium tanks, and medium tanks like heavy tanks; this will be described as accurately as possible in the role model.

Why are you afraid to make the balance +/-1, like in Blitz?

We're not so much afraid as we don't think it will work right now. Now we are making a balance for +/-2, we don’t want to introduce these artificial limits, because then the “tens” will only play with the “tens”, and now the “eights” can create problems for them, this is not a win-win option when you are on “ eight" versus "ten". It will be a bit boring to fight +/-1.

4. Participation in testing

Updated

What are the selection criteria for the test server?

Player selection criteria may change from time to time. Now we are interested in players who have at least one Tier X tank in the Hangar.

Why didn't I get onto the test server, although I meet the criteria?

At certain points in time, we invite different segments of players to participate. It is possible that at the moment the number of players we need has already been invited and the recruitment has ended. Don't worry, all applications are saved in the system and you do not need to resubmit it.

My friend and I meet the selection criteria, he passed, I didn’t. Why?

The system will consider eligible players on a first-come, first-served basis within the invitation limits we have set for the current testing period. It's likely that your friend fell within the established invitation limits, but you didn't.

How Wargamingdetermines who will become a tester?

Since our main goal is to receive the highest quality reviews, we are interested in tankers who are passionate about the game. Sometimes we are interested in certain types of players, depending on what we are testing in a particular case. For example, if we want to test changes for a heavy tank, we will select experienced players in heavy vehicles.

How often are testing requests processed?

We invite participants back every few weeks so they can look at the changes with fresh eyes. We make selections based on the current stage of testing, not the order in which candidates applied.

Why not give everyone access to testing?

The Sandbox provides a small, fast-paced environment where developers can work with target groups of players on Balance 2.0 and experiment with new gameplay elements. This environment should be a positive and constructive ecosystem where testers and developers can collaborate effectively. We are looking for positive and engaged tankers and invite new members every few weeks to keep the Sandbox an active environment.

What rules of conduct will there be on the server?

The same rules apply on the test server and testing forum as on the game servers. Our goal is to maintain a constructive and positive work environment during testing. Therefore, testers who demonstrate toxic behavior towards other participants will be denied access to testing without the right to appeal.

Does Wargaming monitor what is happening on the test server regarding swearing, etc.?

We monitor the behavior of players in the Sandbox in the same way as on a regular server. If you notice someone acting inappropriately in the game, please use the reporting feature. Testers found to engage in inappropriate behavior are deprived of access to the Sandbox without the right to appeal.

How to apply to become a tester?

Any tanker can apply to participate in testing. Visit to submit your application or check the status of your application. If you have access to testing, a notification will be sent to your email and the game client.

I did not provide any information when applying. What do you know about my account?

Once you clicked the “Submit Application” button, your account has been submitted for review. We already know basic information about your account: preferred equipment, nations, number of battles, winning percentage, whether you have any violations, etc. The application process simply tells us that you are interested in testing.

Where can I download the client for the test server?

If your application is approved, you can download the test client on . You can apply for access to the Sandbox there.

Will my account be empty?

Once your application has been approved, you need to wait 48 hours, during which we will prepare equipment, gold and credits to begin testing. There will be no changes to your main account.

How will I receive information about new tests and the start of a test?

The main source of information about the Sandbox is the list of pinned topics on the Sandbox forum that will be created to discuss a particular change. Please note that gameplay features in the Sandbox are not finalized and some may never appear in the game. Unfortunately, we are not ready to talk in detail about all the changes that will be tested.

How can I find other participants for the test?

To team up with other testers, join the general chat in the game client.

Where can I provide feedback on test server content?

You can express your opinion about what you saw on the test server on the Sandbox forum, in a special section.

Why is the test server unavailable?

Sometimes we install updates on the server. At these moments it has the status “Unavailable” and you will not be able to log in. When this happens, try logging in again in an hour or two. If Sandbox is still unavailable, please check the test forum — announcements about temporary server unavailability are published there.

Why is my ping so high?

The Sandbox server is located in Frankfurt (Germany) and has less bandwidth than regular game servers. If you don't usually play on the RU3 server, it's likely that your ping may be higher than usual.

Is there a queue for entry on the server?

We expect some excitement after the updates are installed. If the number of login requests exceeds the maximum number of simultaneous logins supported, you will have to wait in the queue.

Why is it taking me so long to find opponents to play with?

The number of players in the Sandbox is slightly smaller than on game servers, so finding a match may take longer than usual.

What language is support provided in?

The test client will be available in Russian and English. Support from employees will also be provided in Russian, English and other European languages.

Is feedback needed or can I just play?

We are very interested in your feedback, because it is thanks to them (together with statistics) that we will make certain changes in the Sandbox.

About the imminent launch of a separate test server “Sandbox”, on which we will test the new balance of World of Tanks together with the players. This server will allow us to quickly learn your opinion about upcoming changes, and you will have more opportunities to influence our decisions.

What is Sandbox?

“Sandbox” is a separate test server on which developers together with players will work on a new balance of World of Tanks vehicles. But this does not mean that these changes will necessarily appear on the main game servers soon.

Testing in the “Sandbox” will begin this summer; we cannot reveal the details yet, but you will definitely be able to familiarize yourself with the changes for Tier X vehicles at the very beginning of testing.

How to get into the Sandbox?

To get started, submit your application by clicking on the button below. You will be taken to a special page where you will complete your application in a couple of steps.

What are the selection criteria?

Not everyone will have access to the test server. The criteria for selecting participants depend on the objectives of a particular testing stage, but the goal will remain the same - to invite players who are not indifferent to the fate of their favorite game and are interested in close cooperation.

How do I know if my application has been approved?

Tankers who have access to the test server will learn about this from several sources:

• a letter to the mailbox associated with the account;
• notification in the game client.

We will need time to process applications and determine the number of invited test participants. It is planned that the first wave of invitations will fall in mid-June.

Access to the test server may be terminated or limited at any time for failure to comply with the provisions of the User Agreement and other Wargaming rules. Restrictions for actions performed while playing on the test server can be transferred to the player’s main account.

We are waiting for your applications. Together we will make the game better!

you can download special wallpapers and a calendar for June dedicated to the “Sandbox”.

Levels in WoT are from 1st to 6th. How do they differ from the older ones, how best to play at these levels. What

When a player reaches level 10, many questions arise. For example, what level is best to play at? Many people don't like the top levels for some reason. Namely:

In top battles there is often chaos.
Lots of unbalanced machines.
The speed of battle is much higher due to the very high characteristics of the equipment.
Level 10s are very expensive without a premium account.

These or other reasons raise the question for some players: what to play on? You can just go to the playlook website and play a simple online game, but I would like to disassemble tanks in the WOT sandbox. Let's start with the sandbox.

Levels 1-3 of technology in WoT

T1 Cunningham– possesses a cassette that is capable of destroying any classmate with the proper skill.
Renault Otsu– elevation angles and an armored turret do their job when used correctly. The picture is clouded only by low armor penetration.

At the next levels there are several sand titans, namely T18, Pz.Kphw. II Ausf. J, Pz.Kphw. 38H 735 (f). What are they good for? At small levels there is such a thing as armor, which does not exist at higher levels. This indicator at all three levels is off the charts.

Conclusion: you can play in the sandbox, but do not forget that it is very difficult to predict the actions of allies and opponents. If you have the “sixth sense” perk, then you are the king and god of the sandbox.

4-6 vehicle levels in WoT

There are also many unbalanced machines here. We all know about the legendary KV-1S and M18 Hallcat. These 2 tanks are the standard of imbalance in WoT. They'll be nerfed soon. What then will lovers of superiority play in the sandbox? But that’s not about that now. At level 5 there are also many interesting tanks, but not all of them are imbalanced:

KV-1
T49
T-34
AT2

Each of these cars is special. And all have unique gameplay. If you wanted to look into the sand, relax and play with inexperienced players, forget about it once and for all. There is no relaxation in the sandbox; chaos reigns there. You will need to constantly expect something completely illogical from other players. But on these tanks in the top you will feel just great. A couple of crew perks, additional equipment and gear will give you a big advantage in the sandbox. Most players at these levels do not use the above.

This information will help you understand the sandbox and decide whether small levels are right for you.

Then, download and update the client.

It looks exactly the same, only without the various promotions of the game about discounts and premium store offers.

We enter the game, as usual, using our personal data.

Hangar "Sandbox" WoT

The hangar provides all level 10 tanks available in the hangar, as well as all light tanks of level 8 (three nations), fully researched. Each tank has its own crew, with three skills available for players to choose from.

Very strange, but the French light tank of tier 8 - AMX 13-90 - is missing.

The hangar contains initial supplies:

One thousand in-game gold and five million silver are available in the game. Inventories are updated daily by writing off the remaining funds and adding the original amount of monetary units.

The distinctive features of the sandbox can be observed already in the hangar. For example, there is no concept of purchasing gold shells (cumulative, sub-caliber) for silver; it is possible to purchase them only for in-game gold (from 10 units of in-game gold per shell).

Purchasing equipment with in-game silver remains.

Comparison of characteristics of RU 251

The characteristics of all tanks have been changed. The picture shows a comparison of the usual and tested characteristics of a light tank. Where the green rectangle indicates an increase in the value of the characteristics in the tested sample, and the red rectangle indicates a deterioration in the characteristics.

There is no crew on the tanks, but the following modules are installed: Coated optics, vertical stabilizer and improved ventilation.
