Originally, the game was planned for the Xbox 360 platform, but the team turned to the Wii when they received information how the new controller would work.
The only version of the game that got to keep all of the excessive violence and gore was, ironically, the US version of the game, while the rest of the world had to make due with toned down violence and enemies turning to ashes instead of spraying fountains of blood.
The Japanese version was also supposed to be "unedited" but Suda51 changed it last minute without any obvious explanation as to why.
