The physics sandbox Garry’s Mod is. There are no predetermined objectives or goals. We hand you the tools and tell you to have fun. You spawn objects and weld them together to make your own contraptions – whether it’s a car, a rocket, a catapult, or something else entirely – the choice is yours.

You can put a wide range of characters in absurd situations. However, if you want to do more, we can help.
