Conker's Bad Fur Day developer Chris Seavor will release The Unlikely Legend of Rusty Pup on eShop for Wii U and 3DS.
The game is a 2D platformer with mature such as a "serious and adult story," but no swearing or Great Mighty Poos throwing their shit at you.
"It's a very sad tale," Seavor told Nintendo Life. "It's not dark as in 'mature' - it's not got swearing in it, or anything like that. It's quite a serious and adult story, but still a fun and hopefully playable game with lots going on. There will be moments of dark humor, but nothing gory."
Shawn Pile, also an ex-Rare developer, is working on the game alongside him.
The Unlikely Legend of Rusty Pup will release sometime next year.
