According to Russian sources, the German Waffenträger auf E 100 will return in a special game mode:
As predicted, Waffentrager will indeed return in a new game mode! Will be the main “boss” against 7 players. The event is scheduled to start on September 28. Additionally, in the mode you can get boxes with all kinds of cool and unique tanks. It is not known how the mechanics of these boxes work, but you can get, for example, the American T77 from them.
