Please note this is a preliminary set of features for 9.20. We’ll reveal the final details just before release.

Update 9.20 is entering Supertest today, bringing a red-hot array of new features and adjustments. With it, we address your feedback on the stun effect, continue Tech Tree revision, add a 30v30 scenario for Random Battles, and unleash nine new Chinese TDs. While we're still nailing down the final details, we’re eager to get you up to speed with the update, summarizing new features. Shall we proceed?

Supertests happen at the early stages of development—typically a month and a half before final release—and involve checking the changes of a new update and searching for the most critical issues before open testing. World of Tanks Supertests are divided into production tests (new maps, balancing vehicles, etc.), and version tests (the entirety of the update). Once Supertests are complete, Common Tests begin, available to all players interested in trying out new features.

Vehicle Rebalance

This time, we’re focusing on four national lines—Japan, France, USA, and USSR. The German tree is getting a few tweaks, too. As a follow-up to the comprehensive revision it received in early 2017, we’ll be working on combat parameters of the Maus, Mäuschen, and 8,8 cm pak 43 Jagdtiger.

Once we shared the first details on the upcoming vehicle rebalance on social media, they’ve become the most discussed 9.20 topic on World of Tanks forums. So instead of covering them as part of the 9.20 preview, we ran a standalone article on Tech Tree revision to explain the rationale behind the changes and address your questions. Head here for an in-depth overview.

SPG Improvements

The work on fine-tuning SPGs didn’t stop with 9.18. The team spent a few months analyzing your feedback and came up with a set of tweaks to improve the experience for players in arty and those fighting them.

The increased splash radius often resulted in confusing instances where you thought you were safe from an enemy SPG, laying low behind cover, but received damage regardless. To alleviate these issues, we refined the stun and damage calculation mechanic, adding an extra set of variable for shooting over obstacles:

Don’t worry about arty shells if the construction (destructible or indestructible) you use for cover is two or more meters thick and your tank stays completely hidden behind it. You’re safe there: if an SPG shoots, your tank won’t get stunned or damaged.

Tanks hiding behind a fence or a small house that are less than 2m thick will get stunned and receive the same amount of damage they would get if they were in the open.

There’s also a third scenario: while cover is thick (2+ meters), a vehicle isn’t fully hidden (think of any corner maneuver). In this case, the stun duration and damage depend directly on how exposed a tank is. Based on the sizes of the visible area, a vehicle can get:

25% of the total damage and stun time

50% of the total damage and stun time

75% of the total damage and stun time

100% of the total damage and stun time

Also, to provide you a full lowdown on your performance in a battle, the post-battle stats will now brief you on the total stun time you caused.

New Chinese TDs

Nine Chinese TDs are revving their engines, ready to hit the battlefield. Yes, we’re talking about the line that rolled out on Chinese servers a few months ago. We know this is something you’ve been asking for, and we’re excited to make them available for all players. We’ll have more to share on each vehicle as we get closer to release, so stay tuned.
