This is a surprise to us as we actually thought the game was released. Apparently not, for the second closed beta test for GamesCampus' Tank Ace begins on July 26th and runs through July 31st. The second closed beta test will feature a new challenge mode, new quests, updated bases, all-new graphics, and a windowed mode for gameplay.
Additionally, GamesCampus is running five events through the Tank Ace closed beta test; be sure to check it out.
