Garry's Mod was originally a mod for Valve Corporation's Half-Life 2, but was later made into a standalone release in 2006 for Microsoft Windows, published by Valve Corporation. Later updates saw an OS X build added in 2010, and a Linux build in 2013. It is a game where you can do almost anything: Mod, animate, fly, scream, turn into cans, become a cat, shove a pie up someones pants, make the pie become your pants, anything but eat the pie. Garry's mod is a hilarious game and is really fun. -~-~~-~~~-~~-~-. Please watch: "Kres Plays: Tomb Raider | EVIL SACRIFICAL DEMON SITE".
