Aka the Horror Deck. Oldskool entries included, for best experience choose from the menu as it links with the replacement gametype, otherwise funky things happen.
Tested with coop too.
Unreal 225(4), 226, OldUnreal 227 versions and Unreal Tournament supported.
The intro/outro map music works only on openal and perhaps fmod (untested). On Galaxy you'll get no music.
Please enjoy.
