About RoSim 0.4
Roblox's first true simulation experience. Cutting edge chassis tech with full wheel and force feedback support. This game does not use A-Chassis. By paying for early access, you are given a very early version of the game. There is little content and everything you see is subject to change. RoSim's future is shaped by user feedback, and you are encouraged to contribute as much as you can. Published with Linux
