Highly customizable allowing you to tailor the mod to your preference. There isnt a set number of well defined game modes like in a BF or CoD game instead, servers run player-made scenarios with custom scripts and/or mods.

Vastly expands on gameplay with an ocean of features. Arma 3s Bootcamp update looks to ease new players into the game.

Ruthless realism for the ultimate immersion.If I had to solely recommend one mod on this list to you, ACE 3 would be the one. It allows you to carry wounded teammates, adds shortcuts for placing and detonating explosives, adds proper bullet drop as well as shrapnel to explosions, it forces you to wear earplugs if you don’t want tinnitus from gunfire, and much much more. To name a few of its features ACE 3 integrates a complex, limb-based medical system, that allows you to for example address a specific bullet wound in the arm of a fellow soldier. Sometimes, game files become corrupted due to incomplete updates or abrupt system shutdown during gameplay, among other situations. You could be experiencing the crash and launch issues because some of these files are corrupt or missing. This is a mod that is so deep that even Jacques Costaue would have trouble getting close to it. Arma 3 relies on its files to function properly, just like every other PC game. The single greatest mod ever made for Arma III.
