Word used in the Garry's
Mod community (sandbox game). Some custom maps made from players require players to install the game Counter-Strike : Source in order to have the materials and props included in the
map. This is because Garry's
Mod has a feature that allows you to spawn assets from (some of the) other games that also use the source engine (the same engine Garry's
mod uses), so some players create maps that use these assets for players who also has the game required for the
map. But this word is now not used since the July
2025 update that made the game include contents from Counter-Strike : Source and Half-Life 2 episodes by default.
