All the maps were created by Max Ego aka Dilettante. The most notable maps are DM_Cans and DM_Lockout. Copy the files into the Painkiller/Data directory.

Notes:
Some maps were meant to be played with music but music tracks were not added by the author originally so I added them myself.
If you want other music, you can put your own tracks in ..\Painkiller\Data\Music
DM_Game_Over uses the track called game_over.mp3
DM_Rankin uses dm_rankin_mix.mp3
DM_Slipknot_Invasion uses Slipknot_Invasion.mp3
Interesting Facts about DM_Cans:
health with 50 hp,
new sound of jumppads,
new skin of jumppads,
slowdowns effects.
A custom teleport sound was planned to be used for the teleport that restores health in DM_Cans but that teleport was never finished:

DM_Trainstation_BT (BreakThrough) was planned as a destroyed DM_Trainstation with interconnected corridors but only one hole was added next to Gold Armor with a unique jumppad. So the map idea was not completely finished.
DM_Sacredstein (first version) uses two music tracks sacredstein.mp3 and sacredstein_1.mp3 while DM_Sacredstein_SE uses the default music on the joint maps.
