Far Cry 2 was announced by Ubisoft in July 2007, with two large changes from the previous Far Cry games. First, the game use the Dunia Engine, a modified version of the licensed CryEngine by Ubisoft Montreal. The Dunia Engine creates a completely open-world game with realistic physics and destroyable environments. Secondly, Far Cry 2 is more open-ended than Far Cry, that means the player get to create their own stories with the other characters using an advanced artificial intelligence system.
