Off Duty was my third attempt to make a map in 30 minutes, but I sadly do not know how well it timed since I stupidly forgot to start the stopwatch.
It's fun for 2 - 3 people, staged in a warehouse. Plenty of dark corners to jump out from, although do not expect much time for camping! Kind of an experiment, it was created solely for playing with my friends on and submitting to this map vault.
You have four maps that look good, connected they might be really good. By connected, I mean joining them into a single map, rather than level transitions.
Looking at all 4 map's I say good work, well done. Looking at them seperatley.... well, sorry, but I am not inspired.
PS: I didn't kill your rating, not sure who did.
