Map of Second Assault
Letters in italics refer to marked spots on the map. Sector, thing, and linedef numbers in boldface are secrets which count toward the end-of-level tally.


As you step forward you will collect a backpack, plus a berserk and armor on Ultra-Violence (UV) and Nightmare (NM) skill levels; there is also a shotgun to your right that you should collect. Kill the imps and other monsters in the courtyard, then go up the west steps to a super shotgun and chaingun before pressing the lion switch here to reveal chaingunners guarding the blue skull key. Taking the key causes one or two barons of Hell to appear in the courtyard, as well as a pain elemental on Hurt Me Plenty or higher.

Back in the courtyard, press the gargoyle switch in the south wall to enter a room with one or two mancubi, plus an arch-vile on UV and NM; kill them before entering the room as the door will close behind you. Take the red skull key and kill the revenants and shotgun guys/chaingunners that appear, then flip the switch inside the west compartment to reopen the door leading back to the courtyard, where one or two more barons have appeared.

Press the satyr switch in the south-east corner to lower the wall to the north, revealing two more switches that require the keys to activate. Flip both switches to open the doors between them and reveal a third switch, which will lower the exit teleporter next to the start point. Watch out for the imps and arch-vile that teleport to the courtyard after you flip the first two switches.

Other points of interest[edit]

A megasphere is placed inside the teleporter pad on the north side of the courtyard.
