Hallway was downloadable game where the player piloted the Aero Booster through an obstacle course. It was originally an Exo-code unlockable item. The Aero Booster, controlled using the mouse, flew down an infinite hallway with wall panels at regular intervals. As the player progressed through, the panels would become gradually closer together. The Aero Booster could also put on a burst of speed by clicking the mouse.
