Could someone please tell me...

Does anybody know what the hidden trophy is? I'm trying to get all the zombie achievements I can, and I don't know how to acquire this trophy. Also, does anyone else on ps3 have problems with "the collector" trophy? I bought every gun and weapon (frags, Bowie) off the wall and I didn't get it. Any advice would be greatly appreciated, thanks :D

A quick google search could've told you haha. but anyway.

See Me, Stab Me, Heal Me

Fire a Pack-a-Punched Ballistic Knife at a downed ally to revive them from a distance.

As for the other problem, did you buy Claymores? I didn't have any problems with mine. I did it on "Five" because it has one less weapon to buy (MP40), but "Five" is generally harder than Kino, so it's probably easier to do it on it. Not sure if you can do it on other maps as I did it when it first came out.
