Garry's Mod

Garry's Mod (commonly abbreviated as Gmod, stylized as garry's mod), is a sandbox physics game developed predominantly by Garry Newman and later Facepunch Studios. Garry's Mod was originally a modification for Valve's Half-Life 2, but was later made into a standalone game. It is available for Microsoft Windows,OS X and Linux.

Some of his mods are:

• Prop Hunt
• Zombie Survivor
• Corrida dos macacos
• Sandbox
• Trouble in Terrorist Town
• Jailbreak
• Murder
• Role-Play

 Although Garry's Mod is listed as a full game, it has no objectives and instead gives the player a sandbox to manipulate items free of restrictions, although most multiplayer servers offer original game modes created by players. Garry's Mod allows players to manipulate items, furniture, and props – various objects that players can place in-game. Props can be selected from any installed Source engine game or from a community created collection.. The Physics Gun allows objects to be picked up, adjusted, and frozen in place. The Tool Gun is a multi-purpose tool for performing tasks, such as constraining props together, creating interactive buttons, and creating controllable winches and wheels. The Tool Gun is also used to control add-ons created by the community. Garry has shown on YouTube that the player can use Kinect on ragdolls.
