mintybreath: just so you know, it's not a game. It's a sandbox for the physics engine in half life 2 and other source powered games. You can bring in any character model from half life 2 then either have them walk around acting like they would in the game, or use them as rag dolls as position them how you want.
Thanks for telling me, i guess it was just a bad choice of words, as i know what garrys mod is. My friend had it, and we played it all the time, until he moved to colorado. :(
