Base:
New levels from Scratch
Build time:
Editor(s) used:
Doomcad 6.1, Deth 4.19, BSP 2.3, BSP 3.0, Wintex 4.1
Bugs:
Yes, An Arch-Vile can make you jump out a window in the silver switch area and you can get stuck out there in the darkness. So kill him fast. But thats a secret area and simply find the rocket Launcher to kill yourself. Yhers are no other bugs in this level. Plus that Arch-Vile is on UV only.
