A former artist at Rare has given us a peek behind the curtain at the studio's "Savannah" project and the eventual elimination of Killer Instinct. Speaking with NotEnoughShaders, Donnchadh Murphy, who was a 3D modeler at Rare but now works at an animation studio, revealed the developer was working on a project called "Savannah" for Kinect.

Savannah (models pictured) was going to be a Kinect title where players raised a lion cub from birth, teaching the animal survival skills. The game was only ever a prototype and was never greenlit.

Meanwhile, Murphy said, the company was always interested in revisiting the Killer Instinct franchise in HD, as is often requested by ardent Rare fans. "We all wanted to make KI3, but Microsoft [was] more interested in broadening their demographic than making another fighting game," he said. "So it never got made, I doubt it ever will."
