Renegade Kid, developer of ATV Wild Ride 3D and the 3DS platformer Mutant Mudds, has a new title in the works called Treasurenauts. Siliconera discovered a trademark for Treasurenauts in the USPTO and confirmed with Renegade Kid that the game will be announced soon.

Renegade Kid has been a strong supporter of the 3DS, so perhaps Treasurenauts is another 3DS game?
