Garry's Mod 2023.5

Work and play in a sandbox environment based on the Source game engine. Add custom and standard objects, modify their shapes and sizes, add animations and record videos. Develop human models, make films, spawn multiple copies of any object, merge them and customize their placement.

Garry's Mod is a Sandbox Game based around the idea of building. Unlike most other games there aren't any objectives - you can't lose and you definitely can't win. You spawn objects and weld them together to create your own contraptions - whether that's a car, a rocket, a catapult or something that doesn't have a name yet - that's up to you.
