When it was revealed developer Retro Studios wasn't working on Metroid Prime 4 (it had, after all, made the previous three) we were left wondering what the Texas-based outfit would do next - apart from handling the Switch port of Donkey Kong Country: Tropical Freeze, that is. Well, one hot rumour suggests it's been secretly tinkering away on a new Star Fox title, but with a twist you definitely aren't expecting.

The rumour - which was posted by Reddit user DasVergeben on the Star Fox subreddit - says the dev is building a spin-off more akin to F-Zero than a traditional Star Fox title - one purportedly called Star Fox: Grand Prix. Here's the full post below:

"What Retro Studios is working on is a spinoff based on an existing Nintendo IP that they haven't worked with before.... Star Fox.

It is actually a racing game. Something like Diddy Kong Racing mixed with F-Zero essentially. But more like F-Zero gameplay. It will have a adventure mode of some kind (think Diddy Kong Racing) and there will be some boss fights and a hub world like it too.

It is called Star Fox Grand Prix."

Take this one with a big pinch of salt. With E3 less than a month away, this is when rumours go into overdrive, especially those with big Nintendo licenses attached. However, considering how the Star Fox licence has struggled to match the high points of yesterday, a new direction might just be what the franchise needs.

Share your thoughts below on this interesting rumour and whether you think Fox and co will be taking their Arwings to the track instead?
