As being full sandbox, you are a bitch if you want hacks for it.
Also, why would anyone just kill themselves and hack?
That is "minge" stuff
But it has some aimbots, what shoot at corpses until you aim away and back. And wallhacks.
Garrysmod dot org has some. Just search for "Hack Pack" and it comes up. ON SITE MADE BY GARRY HIMSELF :O
