Advanced Combat Environment (ACE) is a full conversion modification for Armed Assault. The overarching philosophy of ACE is to provide its users with a combat simulation that is both realistic and enjoyable. Our primary mission is to create a wide variety of real world weapons, vehicles, equipment, and tactics so that those playing the ACE modification will be able to better simulate combined arms combat on a modern battlefield. ACE is designed from the bottom up with the goal of encouraging its users to employ real world tactics and strategy (fighting as a team) in order to accomplish realistic military objectives. We strive to create hyper-realism without losing sight that the mod must be playable by the “advanced” user. Our focus is not only on creating coding and scripting which highlights realism but on creating realistic missions on which one may experience the full spectrum of virtual combat.
