• Ten new maps, all winning entries in Tripwire's Custom Map Competition. Highlights include:
  
  “Smolensk Stalemate”: the contest winning map features perfectly balanced to-and-fro infantry combat through ruined villages and trenches in August 1943.
  
  “Leningrad”: features close-quarters infantry fighting in the ruined streets of the city, above them in the bombed-out buildings and deep beneath them in the sewers, all with close-in armor support.
  
  “Berezina”: the After-Hourz team surpass themselves on this rural/village map, introducing not just a new vehicle (the Russian BT-7 light tank), but also the first functional anti-tank gun in the game. To cap it off, the BT-7 even carries tank-riders.
  
  “Black Day July”: one of the very best for tank combat fans, set in the rolling countryside around Prokhorovka as German and Russian armor clash en masse during the Battle of Kursk.
  
  
• Increased multiplayer count. A new level of intensity with 50+ player multiplayer battles (up from the previous limit of 32).
  
  
• New community made content, including the Russian BT-7 light tank with infantry tank riders and the first player controllable anti-tank gun in the game.
  
  
• New soundtrack: The “Orchestra” comes to the Ostfront - the game now features a complete in-game soundtrack from composer Matthew Burns.
  
  
• Gameplay enhancements. The addition of several features requested by the clan/ladder/league community to enhance competitive play.
