Gameplay at this stage takes place between two separate interfaces: the Terminator View Screen, where the player takes direct control of individual Marines, and the Planning Screen, where orders are issued to the Marines by clicking on command icons. The player's Marines begin each mission grouped together at one or two starting points of the operational area, while Genestealers continually enter the mission from marked entry points. On the Planning Screen, orders are issued to the Marines while they come under Genestealer attacks. In the campaign, Marines who survive a mission gain experience, improving their combat abilities and chances of survival for future missions. For certain missions, the player can customise the squads' armaments, selecting from 10 other weapons, such as Heavy Flamers for destroying targets and the Chainfist for opening locked doors. Marines are usually are equipped with a gun-the Storm Bolter-for long-range combat, and an energised glove-the Power Fist-for hand-to-hand fighting. Before a mission, the game briefs the player on the objectives and shows a small map of the operational area. The remaining missions are tutorials designed to help players learn the game and standalone missions.

The game features a time-limited option to pause the action while enabling the player to continue issuing commands.

Using overhead maps, the player orders the Marine squads, and controls individual Marines via first-person shooter interfaces. Drifting in and out of the Warp-an alternate dimension used to cross interstellar distances-these vessels are infested with the four-armed Genestealers. The game takes place aboard huge derelicts known as space hulks. Space Hulk was developed and published by Electronic Arts, with support from Games Workshop.
