This whole thing is absolutely kickass. The characters are awesome, the guns all feel nice, and the maps are great. I'm only sad it'll be ending eventually ;p
I do have one question though, is it possible to get the space cats hud to work when you're playing other megawads? I've tried it on a couple and it never seems to work right. Maybe it's just that most of the map packs and wads I try also mess with the hud or something?
