Then we can put enemies and NPCs – nothing prevents us from putting hordes of zombies in City 17, or putting gentlemen in tuxedo behind roaring cannons of World War II. This allows us to create any environment: futuristic scenery from Half-Life 2, battlefield of World War II from Day of Defeat, or to set horror-like atmosphere known from Left 4 Dead series. This gives us access to thousands of models, weapons, characters, skins or items from a huge library of Valve’s games, as well as modifications and scripts made by players themselves, using Lua programming language, and published in special workshop on Steam platform. To fully enjoy possibilities offered by Garry’s Mod, we just need to have any game that uses Source engine installed, for example Half-Life 2, Team Fortress 2, Counter-Strike: Source or Left 4 Dead.
