To pass the "4-switches" barrier on Doom II map Nirvana: First, Activate all four switches, and then walk up to the raised platform and Activate it like a switch. The edge of the platform will drop down momentarily, allowing you to get on and ride up. From there, you can simply walk down to the far side of the room. PC Doom2 players can click here to access a demo that shows how to get past this barrier.Back to: Doom Help page / Classic Doom home page
