Hi guys, I just did a singleplayer map that's a maze, there are 35 monsters to kill, and it's not too hard to find the exit. Even me got lost!
I think StealthQuake is great to play with this map! But the halls are thin, and it would need some modifications, when I get time, I'll test.
Here's it (only 115k):
