Many levels have a complex floor plan, made more complicated by the use of teleporters that connect different locations on the same level. As players explore a level, the areas they visit are automatically mapped, and the player can bring up this map at any time. The game HUD shows the status of shields and oxygen, the inventory, and a motion sensor. The motion sensor tracks the movements of nearby characters relative to the player, distinguishing between hostile creatures and allies. On some levels, the motion sensor is erratic due to magnetic interference. Weapons reload only when the current clip is exhausted. At any time, the player can swap their held weapon for another in their inventory; this includes gauntleted fists for delivering melee attacks, which do increased damage when running.
