Nice job on the vid. Maximum Patience to actually kill them all

.
Watching Part 1 makes me think that map would make for a good starting point for a CO-OP MP survival type level...
yup

the first part is the hardest - because there are 2 heavies and i think 5-6 commanders + lots of grunts....
rest of the level isnt too bad as long as you think about what you're doing!
