The game is a third-person shooter. Rogue's primary arsenal are his pistol and assault rifle, with the latter being upgradeable throughout the course of the game. The rifle may be outfitted with a silencer at any time, or deployed as a sentry turret. As the game progresses the player unlocks the ability to outfit the rifle with a sniper attachment, a shotgun attachment, a cluster mortar attachment, an anti-aircraft rocket launcher, and an electric beam rifle. Other weapons include deployable micro mines, incendiary grenades, scrambler grenades, fragmentation and sticky grenades plus heavy machine gun posts and flak cannons scattered across the field with occasional use of lazooka rocket launchers and hell cannons.
Rogue's survival is ensured through clever use of the battlefield, which is generally rife with cover. He is able to fire while stationary, on the run, crouching, diving, and around the corner of any form of cover. Rogue also has the ability to unleash suppressive fire, which consumes a small amount of ammo and fires blindly from cover to intimidate enemies and cause them to find cover of their own. Enemies are highly susceptible to headshots, which will generally down them in a single strike. Another feature of gunplay is the ability to shoot an enemy soldier's air tank. Targeting the head displays a skull and crossbones, while targeting the gas tank shows a rectangular shape. Penetrating an air tank will cause enemies to run frantically and then explode, damaging any other enemies nearby.
Rogue may search fallen enemy and ally bodies to recover Salvage, the game's main resource, and a necessity for purchasing any of Bagman's supplies. Salvage is used to create all forms of ammunition and grenades, med-kits and arsenal upgrades. Scrap piles may also be found and looted for a considerable amount of Salvage.
