A physics toy box, Garry’s Mod gives you countless tools and assets to create your own games, videos or weird experiments, even if it’s just making Team Fortress 2 characters pull silly faces. The system requirements are low, so you’ll only need a DX9 capable GPU and a 2GHz CPU. This physics playground is one of the best sandbox games on PC.
