Despite spectacular graphics and strong attention to simulating real-life combat weaponry, ArmA: Combat Operations falls victim to some major bugs, one of which causes those graphics to fall apart. Additionally, the weight of its complicated menu system slows down the game's pace. It appeals to hardcore enthusiasts who appreciate details like realistic rifle drift, recoil and a selection of over thirty different weapons. Furthermore, the multiplayer component, which supports up to 100 simultaneous players on one gigantic map, supplemented by an included map editor, shouldn't be scoffed at. However, more casual players might feel left behind.
