I'll I've noticed was that you can crawl on the top edge of the vents u can run up, and also get on double tap 2.0 also I noticed that when teammates were down they didn't have the Revive Icon showing. idk if this is due to your crawling while down script making the game they are prone and not down.
Without camping at round 20 finished, bought the buyable ending without downs. I was going to say it's an easy map but training can be tricky, lucky the F2000 was pretty good for me and Bubbles as well. Good job man, enjoyed it as my first custom zombie map I played in a WHILE.
