Cenodrome is a small standalone map made in the mold of the TWHL Tower maps. TWHL Tower was a collaborative mapping project where each mapper constructed a small floor of the tower, and each floor was joined to others by a stairway. Cenodrome is the long lost sub-basement of that tower.
Edit:
That was great. Very clever entity work, and funny to boot. I don't even know how you managed it all. Short, yes, but in the context of a TWHL Tower map? You did an awful lot with that little space. Nice textures too, it looks really sharp for a Goldsource map! Good stuff!
Though I was able to bug out one of the test chambers, not sure which one it was, but it included the option to nuke any lives remaining, when you then jump into the new chamber it just triggers an autosave/loading loop?
Edit: Okay finished it. The last round was pretty tough, not sure if it's just me. Once you got the egon I had to hide in a corner basically because I only had like 30hp left, so one strike from a vort and I'd be dead.
