Belial's Bad Brain is a single-level PWAD for Doom II meant for limit removing source ports. It was designed by Alexander S. (Eternal) and uses the music track "Somewhere Over the Horizon" by Mark Klem, originally from Requiem.

The second of Eternal's slaughter maps, Belial's Bad Brain originated as a four-hour speedmapping submission to a contest held on Doom Power, and was later modified and greatly expanded for its standalone release.
