I've got chams for PB (
) and some maps (Desert Camp, Kick Point, Red Rock, the new mall map, maybe some more) won't work. It's the way they made the maps, rocks, walls and other obstacles are "integrated". Meaning that if you have Wallhack on, these obstacles become invisible, and with chams they become "chammed". You can play with them, but it looks fucked up.
And for the record, I very much dislike the site that I got the chams from and since this is out I've deleted all that shit cause I support MPGH
