Plasmaplant was originally a "plasma and pistol only" idea for my now venerable Cabal series, and so the map is based off an almost 20 years old paper sketch. I changed the layout and style but kept the central gameplay ideas.
19 furious CTF maps
Episode 4 replacement for the Ultimate Doom which may or may not be related in any shape or form to Concerned :P
