Brick Rigs
Brick Rigs is a physics sandbox game that allows you to build, drive and destroy almost any type of vehicle imaginable. Whether it's a dragster, fire engine, forklift, helicopter, plane, train, ship or even a tank, you can probably build it in Brick Rigs.
You can also upload your creations to the Workshop to share them with the community. And if you don’t feel like building anything, you can just download any of the over 200,000 creations already uploaded by other players.
The multiplayer mode allows you to experience these physics together with your friends. You can organize races, demolition derbies, dog fights or emergency scenarios. The rules are up to you!
