Detailed Mechanics of Continuous Fire System Guns:

The Vz. 71 is equipped with twin guns. This type of armament isn’t new to the game. The tank benefits from the new mechanics: high rate of fire with minimal individual shell damage. The guns fire alternately with a reload time of 0.05 seconds between shells. The high rate of fire introduces a new parameter—damage per second. Currently, at Tier 10, the average damage per second is 240, assuming all shells penetrate. The poor accuracy and penetration will encourage players to flank enemies to maximize damage output.

Additionally, the tank will have a new sight that shows the magazine’s fill level.

This new mechanic will also appear on Tier 8 and 9 tanks in the new Czechoslovakian light tank line. The transitional Tier 7 tank will not have this mechanic. The premium Tier 8 tank also features twin guns with this mechanic.

  1. Looks like another light/medium hybrid, it’s pretty large and camo is on the meh side. Hard to pull ambushes with EVEN 90, Manticore, and French gokarts running around.

    Still, a tank without gold ammo in 2024, amazing. Might be worth grinding just for that.

      1. Check the pictures and provided data, the second ammo type (APCR) trades damage for penetration and shell velocity and it does not have red stripes that indicate it’s a “special” type of ammo (there’s only one black band, which identifies APCR ammo). Credit cost of APCR is also lower than stock AP.

          1. It’s a trade, one picks either alpha damage and module damage or shell velocity and penetration. A welcome change compared to the current state of ammunition where premium ammo is always the superior choice.

            1. That’s why it’s called premium ammo. No doubt this will be corrected in the next reiteration

          2. good luck targeting weakspots either way with the autocannons. its all about going after sides and rears at closer ranges. 250mm should be enough to do SOME damage to the side and ass of a super heavy but 190mm is more than enough for everything else.
