According to news site “Nintendo Everything”, a document revealing plans to release Painkiller on Wii U was recently uncovered. This is not confirmed so take the details with a grain of salt.
Here is what the document says:
“The Farm 51 Group developer has obtained an official game development license for the Wii U, whose premiere is planned in the fourth quarter of 2012. It should be noted that unlike the Xbox 360 platform and PlayStation 3, which are available on the market for several years, the opportunity to create games for the Wii U before the planned market launch is made available only to developers who are are planning to release titles in the coming years particularly of interest to Nintendo. In this case, not only the history but experience and current status of the issuer was analyzed, as well as the market potential for future products. The issuer has taken this action in cooperation with the publisher Nordic Games, in plans involving production and release of new games in the series “Painkiller” for the Wii U.”
