This game was teased for awhile. Some ex RARE guys started thinking about making a game like this while teasing it on this twitter account https://twitter.com/MingyJongo It went on for awhile and was seemingly dead. The account came back out of no where and started saying seemingly random things like ctrl+alt+delete (rebooting the project) and then Grant Kirkhope teased a reveal on this month's edge that would appeal to BK fans.From what I remember, the twitter account expressed interest in using the Unity engine, but that might of changed since they stated that.
