The game is viewed from a first-person perspective. The objective is to complete mission goals while navigating outdoor battlefields, bases, villages, bunkers, and underground passages.

Players explore levels, collect weapons and ammunition, engage enemies, operate usable objects, and survive scripted combat encounters. Progression follows a sequence of campaign missions rather than a branching structure. The DOS version also includes multiplayer support, although the exact available modes can depend on the release and configuration.

Conserve ammunition for weapons suited to each situation, especially when moving through longer missions with limited resupply. Check side paths and buildings for supplies before entering major firefights.

Use cover around bunkers and fortified positions, and avoid charging into tunnels or rooms without checking likely enemy locations. Learn the layout of each objective area, since scripted ambushes can punish rapid movement.
