The game is played from a first-person perspective across a sequence of mostly linear stages. Players move through bases and industrial sci-fi environments, fighting enemies, collecting keys or activating switches, and searching for the exit. The N64 version adjusts level layouts and controls to suit the controller, with an emphasis on movement, aiming, weapon switching, and resource management. Health, armor, and ammunition are limited, so exploration and route knowledge matter. Some stages include platforming, hidden rooms, and optional pickups that reward careful play.

Learn the locations of ammo and armor pickups so you don't run dry in later stages. Use your strongest weapons on grouped enemies or tougher foes rather than wasting them on minor targets. Check corners, walls, and floors for hidden switches and secret areas. In harder fights, keep moving and use cover or doorways to reduce incoming damage.
