Several are forced to leave Codemasters after the flop with Onrush

Evolution Studios, known for the exclusive PS4 racing game Driveclub was closed by Sony 2015 and was later taken over by Codemasters. Under the leadership of Evolution leader Paul "Rushy" Rustchynsky began to develop by the explosive arcade OnRush released on June 5 this year.

We wrote a few rounds on OnRush earlier in the spring, but your reception was cool at least. Now, it turns out that you have not been alone in asking questions about the game because Codemasters gives several members of the old Evolution team. The sources tell Eurogamer that several people who worked with the development of OnRush left the company or were invited to be interviewed again to maintain their current services. The feeling among those who stayed is that the team in the future will help other parts of Codemasters or will work with "safe projects".
