i want to play garrys mod no downloading and no buying
Well you have to have steam to play garrys mod so tacticly you have to get steam first and than you can download garrys mod. :)
no because garrys mod requires that you have a game that uses the source engine
gmod is 10$ at garrysmod.com
It costs about $10.
Yes, you can play online multiplayer.
You can get Garry's Mod 9 for free, yes. But Garry's Mod 10, (11), you have to pay for. But Garry's Mod 10 is really worth it, in my opinion.
Buy Garry's mod 10 off of steam.
