What is SpaceBuild for GMod?

Spacebuild is an addition to the video game "Garry's Mod." The Spacebuild addition to the game lets users take their adventures into space by building spaceships and life support systems.

"Garry's Mod" is a popular sandbox game that lets players build their own world without linear progression or limits. The game gives players a map and tools to create basic items. These basic items are then combined in various ways to create more complicated items, such as cars, buildings and airplanes. Spacebuild is a later addition to the game that lets players combine items to make spaceships with which to explore outer space.
