Garry’s Mod is a sandbox mod for the Source Engine. Unlike normal games there aren't any predefined aims or goals. Players are given tools and are left to entertain themselves. The player is in a world where objects can be created and destroyed on demand. Where people can be created and destroyed with the click of a mouse. A world made for him. A world he made.

btw, if you're willing to crack steam and pirate gmod, i don't recommend it, since, you won't be able to download stuff from gmod.org, but since there are many pirate sites where you can get gmod stuff, i won't make a stand, but i warn you, not only you won't be able to play multiplayer, that you won't be able yo use the toybox, it's got the best weapons, npcs and maps.
also, make sure to troll a lot on rp servers.
