Arma III is as complex and realistic as military shooters come. It’s a combined arms game, so you’ll be driving, flying and even scuba diving through conflicts and missions. An Intel Core i5-2300/AMD Phenom II X4 940 and a GeForce GTX 560/Radeon HD 7750 is recommended. Not only is it a great shooter, it’s one of the best sandboxes on PC.
