Welcome behind the Iron Curtain! Take a look at what life behind the barbed wire could have been in an alternate universe of the 1980s in Czechoslovakia and its border with West Germany. Ride, fly, or run into battle against your enemy in an all-new lush and mountainous terrain. Conduct large-scale mechanized infantry operations, Special Forces raids and long-range reconnaissance patrols deep behind enemy lines. Choose to be a member of US Armed Forces, Czechoslovak People's Army, Independent Rebels, or even play as a civilian. It's all up to you!

The 256 km2 Gabreta Terrain

This map depicts the southwestern border area of 1980s Czechoslovakia and West Germany. The vast border area divides the map into two different worlds. This contribution of Czechoslovakia to the Iron Curtain stretches through a diverse terrain of rivers, valleys, and mountains. Meeting your enemy on the field of battle will make you fight for both urban and country areas while operating from field camps, military bases and airfields. If you get tired of fighting your enemies, you can just wander into the woods along tourist trails and visit various landmarks including a large castle, a dam, caverns, mines and other interesting places.

Terrain features

  • Buildings characteristic of 1980s Czechoslovakia and West Germany.
  • Various military outposts and radar installations.
  • Railway network.
  • Large bodies of water representing rivers, swamps, and a large dam.

Originally founded in early 2001, the CSLA Studio team focused on the history of the Cold War era in Czechoslovakia since the first Arma game, Arma: Cold War Assault, was released. Putting thousands of hours into making community modifications, the team earned the respect of the Arma community. Expanding and utilizing their experience, the team is now taking their work to the next level with their CSLA Iron Curtain Creator DLC.
