Renegade Kid is an indie game development company known best for Dementium: The Ward, a first-person horror game for Nintendo DS, and Mutant Mudds, a 2D platformer which tells the story of a boy named Max as he tries to thwart a "Muddy" invasion. Siliconera recently discovered a trademark for the title Treasurenauts buries in the United States Patent and Trademark office and reached out to Renegade Kid for further insight.
Renegade Kid confirmed that they are, in fact, the owner of the trademark and that the next game will be called Treasurenauts. We don't know how it will play or on what system it will launch, though 3DS seems like a safe bet. Let's just hope people can keep it straight from Scribblenauts, 5th Cell's popular series of games.
