the building is presented in a two-dimensional cross-section on screen, showing the locations of guards, doors, switch panels, lights, security cameras, and other features, including the target objectives. the player, as conway, can run and climb on walls, use stairwells and elevators, and using the abilities of conway's "bullfrog" hypertrousers, can launch the character great heights or distances, potentially tackling guards or breaking through glass walls. conway can survive long falls, but can be killed by a single gunshot, thus requiring the player to stay out of the guards' line of sight.
