Q3DM15: Demon Keep

The Map[]

An Easter Egg can be found on this map. Near the doorway of the lower level, there is a severed head of one of the id Software interns, Eric Webb. His eyes will turn white periodically.
The BFG10K can only be reached via rocket jump.
This is the only Quake 3 map to feature pendulums.
