Is the "post-apocalypse" scenario in a urban type environment?
Ballahack does have a small "town" of about half a dozen buildings which they use for CQB fights, but it's mostly woodland and swamp. They're building some extra "townships" for the Apocalypse game, several of which are likely to be burned down over the course of the weekend (the owner has intimated as much in briefings recently).
How exactly does one "play" with Airsoft guns? Do you just go on honor whether or not you get hit? I mean, paintball is usually pretty obvious when you get hit. Airsoft is pretty cool though. Never thought about competitions with it.
