Gmod, a sandbox physics game, is based on the modified version of the Havok physics engine taken from the source engine. Building contraptions is one of the most fun activities in Gmod (Garry’s Mod), so the modified version of the Havok Physics engine enables you to build contraptions with a bang.
There’s a misconception about Gmod that it is all about teaching & learning physics rules being it a physics sandbox game while the actual fact is way off beam. This is because of the fact that the modified version of the Havok physics engine works based on the laws of physics.
The best part about the engine is that it allows rational stimulations of experiments and structures.
Well, Gmod is a very exciting and appealing game that can be enjoyed both as single as well as a multiplayer game. Players looking for thrills and chills love these kinds of games!
