According to producer Mike Zhivets, “Update 8.9 will introduce the Team Battle mode, significantly adding to the competitive component of the game. The new combat scenario will allow tankmen to form teams and master their tactical skills, fighting against players with similar level of expertise.”
The patch adds a second line of German Tank Destroyers that go from Tier 4 to Tier 10. Armor in that line include the Marder III, which was originally built to combat Soviet T-34’s, the Tier 6 Nashorn, the Waffenträger auf Pz.
The Northwest battle arena is also included in the 8.9 update, which takes place in a woody North American setting, and the Erlenberg arena gets the Encounter battle mode, too.
