The game uses a first-person perspective. Players move through linear missions, complete objectives, fight enemy soldiers, use mounted weapons, and perform occasional touch-screen interactions or equipment tasks.

The campaign is divided into story missions set across military and covert-operation scenarios. Progression comes from completing objectives and advancing through the mission sequence rather than from a character-leveling system. A multiplayer component is also included, with modes and features constrained by the Nintendo DS version.

Conserve ammunition during ordinary encounters and use cover before advancing. Check the touch screen when an objective calls for equipment, map, or interaction use.

Mounted weapons and scripted vehicle sections are usually objective-focused, so prioritize the marked targets rather than chasing every enemy. On harder settings, move between cover after short bursts and reload during safe pauses.
