[dungeon]

Theres a plugin on here which gives you invisible, no clip and god mode all in one go which was designed to detect aimbots. The author wrote it so you can lose health but not die so you know when you have been shot.

I think its called noclip+ or godmode+ or something similar.

Edit

Its called Godclip - http://forums.alliedmods.net/showthread.php?t=101305
