Several infected Marines approach Johnson, prompting him to run into a hallway. He locks the door with a spoofer and proceeds down the hallway. An infected Marine fires a shotgun at Johnson. The pellets hit the wall, missing the sergeant by inches. Johnson dives to the ground, firing the remaining rounds in his assault rifle into the combat form, ripping its head off but not killing it. He then shoots down the combat form with his pistol. He makes his way across a light bridge, jumping onto the other side just as a combat form shuts the bridge down. As he jumps across the chasm, he throws a grenade behind him. The explosion kills his pursuers, knocking him to the ground. He steps onto the lift, glad to have finally escaped the Flood.
