WoT Update 1.21.1: Common Test 1 Has Arrived!

Overwhelming Fire: Try Out Vehicles With Automatic Cannons!

Heating things up this summer is the new Overwhelming Fire event! It will feature eight modified vehicles of the same tier but different types, equipped with fast-firing automatic cannons.

Each vehicle has its own strengths and features unique gameplay, so every Commander will find a formidable tank that best suits their individual playstyle. Each of the eight modified vehicles will have its own firing sub-mechanics based on the mechanics of automatic cannons. All these unusual vehicles will only be available in the Overwhelming Fire event.

During the Common Test, you can try out three of these unusual vehicles:

XM551E4 Hailstorm
(XM551 Sheridan)

Flakpanzer VIII Flakmaus

M5YE2 Thunderclap

The remaining five vehicles will be available when the event goes live, so stay tuned if you want to try them all!

How to Access Overwhelming Fire on the Common Test

  • In your Common Test Garage, click the event banner in the lower-right corner.
  • Or choose the Overwhelming Fire mode in the drop-down menu to the right of the Battle! button.

Players with low-spec CPUs and graphics cards may encounter performance issues when running the mode. To avoid them and play with maximum comfort, change the graphics settings in your game client in accordance with the capabilities of your CPU and graphics card.

During the Common Test, we want to test the technical stability of the gameplay innovations this event features. Based on the results of this test, we will decide if the event is ready to run on the main servers.

Battle Pass Season XI: Test an Additional Time-Limited Chapter!

An additional time-limited Chapter of Battle Pass Season XI will be available for preliminary testing the day after the start of the Common Test. This Chapter features two reward tracks: Base Rewards and Improved Rewards.

During the Common Test, we only test Chapter mechanics. The progression system, values, all rewards, and various characteristics are not final and are subject to change after the Chapter’s release. We’ll share the start time of the additional Chapter at a later date.

The main test reward for this extra Chapter serves a purely technical role—when the additional Chapter hits the live servers, you will receive a brand-new mystery Premium vehicle as your main reward instead. It will be available in the Base Rewards Track.

Join the test and share your impressions of the Overwhelming Fire event and other features!

Scenario With Unusual Combat Rules and Balance Changes in Frontline

Join epic 30v30 Frontline battles with updated Combat Reserves and other balance changes. You can also experience the new Overwhelming Fire event, featuring unusual vehicles with automatic cannons, and test an additional time-limited Battle Pass Chapter.

This August, your favorite game mode will return to World of Tanks with epic 30v30 tank clashes and enjoyable rewards! Its core rules and mechanics remain unchanged, so you’ll feel right at home. However, for this launch, we’ve updated the Combat Reserves system, introduced a scenario with unusual combat rules (Random Combat Reserves), and made a few other minor balance adjustments. Check them out.

Addition of a Fourth Level to Combat Reserves

The maximum level of Combat Reserves is now 4. To activate the fourth level, you need to purchase this Reserve before entering battle using Combat Reserve Points. After doing this, when you open this Reserve in battle, you will already have it at Level 2, and the maximum upgrade level for it will be 4. All default Combat Reserves (Artillery Strike, Recon Flight, and Inspire) will be considered purchased and can be upgraded to Level 4.

The additional Combat Reserve Level opens up new tactical opportunities for every Frontline player. Take the chance to overpower your opponents at critical moments and turn the tide on the battlefield!

Scenario With Unusual Combat Rules: Random Combat Reserves

This scenario is only for the second launch of Frontline 2023.

Random Reserves is a new Combat Reserve selection system. Now, when you enter battle and reach the Ranks where Reserves are unlocked, you will be offered a choice of two Random Reserves. This choice will be repeated until all three Reserve slots are filled. The ability to choose will be available until you make your selection. When your vehicle is destroyed, it becomes available again after respawning.

During the battle, you will have three opportunities to choose which Reserve you want from two options. You may be offered to re‑select an already applied Reserve, for example Airstrike. You can use them independently, and each of them will have its own cooldown.

An exception is the passive Engineering Reserve. When re-selected, your Engineering Reserves merge into one slot and gain enhanced parameters.

The Reserves you choose apply throughout the battle to all the vehicles you play on.

Artillery Strike, Airstrike, Smoke Screen, Minefield, Recon Flight

Field Repairs, Inspire, Sentinel

Putting Reserves in the slots in the Garage increases the chance that they will be offered for you to select during the battle.

Join the Common Test and rock the vast Frontline battlefields again!

    1. it is, already on the 1.21.1 CT so it can be seen on tanks gg, it is literally describe as 75mm XM247 ARES
      the Sheridan is armed with the 37mm T250 from Vigilante air defense system
      the ones on the MAUS are probably ported directly from WoWs, those dual 88s are pretty common on German ships

  1. Didnt they use Arcade mode or some other wierd mode to test stuff before? Or atleast thats what the community thought.

    So considering they teased autocannons in the “Future of World of tanks” video maybe this mode is a way for them to test autocannons at a larger scale before moving forward with the new mechanic.

  2. They fucked up the combat reserves for this month’s frontline and now they want to change them twice again?!
    Just leave shit alone that works and try fixing the broken stuff.
    WG totally incompetent

  3. I’m really concerned about the autocannons. I play Armored Warfare, and autocannons there can be obscenely OP – show pennable armor to them, and get melted in seconds. I don’t trust WG to do balancing right anymore so, I don’t look forward to what’s going to happen.

    1. I played all 3 tanks last night and… accuracy isn’t that great in sustained bursts.
      Neither is the damage per hit, then again, that Yohstrocity has like 4200 hitpoints or something.
      That sheridan one was the least fun imo, and the Flankmaus felt like it had a low-tier autocannon-ish thing like we already got.
      The Yohstrocity was fun though.

    2. it actually gets higher pen than the 152mm from the normal Sheridan
      152mm pen with 152mm HEAT/gold, which is absurdly low at Tier 10 specially since HE nerf, vs 170mm from 37mm HVAP
      this is obviously a test for auto-cannons, to see how receptive those are for the player base, but the final “standard” auto-cannons probably won’t be as powerful
      since this is an event they can “stretch” their capabilities a little but and make players a bit more excited for the prospect of auto-cannons at top tiers

    1. This is just to attract more “kids” to this game. As it’s only for old knobs who keep dying

  4. Ao this ia where our money is going to, instead of balancing mechanics and making the game more pleasant to not only keep old players but we’ll come new ones in a good balanced game they just launch these reee events to keep your mind our of the real problem, I have to give a clap to them since this is a waist of time and resources but who knows what type of loot boxes are coming with this new event.

    1. I mean, clearly this is a test for how they implment auto-cannons into the actual game, like they said in their road map. Most of the events wg has apart from things like frontline have some sort of testing element. Like with arcade cabinet being the first place to test night maps

  5. I’m so glad that I uninstalled after the crew disaster now I just watch Mighty Jingles
