Dead Space 3, which is set for a February 2013 release, is not coming to Wii U as of now, according to Visceral Games' Steve Papoutsis, who is the company's vice president and general manager as well as an executive producer for the Dead Space series.
Papoutsis was asked by a fan on Twitter about the game's possible Wii U release. He replied, simply, "not currently in the plan."
We know that EA has at least two other Wii U games yet to be revealed. We learned at E3 2012 that Mass Effect 3 is definitely coming, and Madden and FIFA are likely coming as well. Madden and FIFA are likely included the "at least two other games," which will be revealed at some point this summer, according to our sources at EA.
Well, even though I'm sure EA bases all their decisions on money, and money alone....if we lived in a strange alternate dimension where EA considered game design, gameplay, and the feasibility of such in terms of hardware platforms....I don't see Dead Space as a whole working well on the Wii U. How would they use the Gamepad screen? It seems like one of the central UI tenets of the game is an economy of iconography on a single screen. There are no menus or inventory screens (well, kinda, but not really, because you always view Isaac's backside and the surroundings). They've integrated everything onto the main screen, and the blue light pretty much eliminates the need for a mini-map. So except for maybe a lock-picking or computer-hacking mini-game (and if I get paid a nickel every time a Wii-U game will use that in the next 5 years, I will be a rich man) what could they throw down there on the gamepad?
