Garry's Mod, a popular standalone sandbox title on Steam, hit its ten-millionth copy sold over New Year's 2015.

This comes from creator Garry Newman's Twitter, where he announced the landmark sale.


Garry's Mod, sometimes known as GMod, was originally a mod for Half-Life 2. In 2006, Newman formed Facepunch Studios and released the standalone Garry's Mod, as well as last year's Rust. GMod allows players to toy with the Source engine in a number of ways, from playing games of hide-and-go-seek as inanimate objects to recreating full movie trailers.
