There is no mention as to the possibility of this port from official sources. Grasshopper Manufacture, Killer7's and Heroes producer, has the game listed only for the Gamecube and Playstation 2. However, the chance of experiencing this nifty psychological shooter for the Wii cannot be denied...yet.

Stay tuned here at QJ for more updates!

The interest this (referring to the Wii symbol on the website) seems to have generated on the internet is quite gratifying, but we're going to have to disappoint you this time. The innovative control system of the Wii would seem like a good match for the innovative gameplay of Killer 7 and we cannot completely rule out the idea of a Killer 7 Wii at some point in the future. However we can confirm that there are no plans at the present time to make such a game and there is certainly not one in the pipeline that we are not telling you about.
