A downloadable mod

KEYMASTER is a gameplay mod for GZDoom 3.0 or later that works with almost any Doom or Heretic level.

On every level a random monster is made THE KEYMASTER, tougher and faster than its comrades. Level exits won't work until you've killed THE KEYMASTER and claimed the key. But you can't damage THE KEYMASTER until you find THE ARROW OF SLAYING somewhere in the level. To find it, watch the icon on your HUD and listen for the pulse sound; it'll get quicker as you get closer.

Levels with no monsters, no pickups, or no exit switch/teleporters (eg boss
levels) will give an error and behave normally.

Configuration options are available, see the included readme for details.
