One of the first game's to be announced for the Wii U was Darksiders II, when it was shown at E3 2011.
A new video from Game Informer features a discussion with Vigil Games, who are developing Darksiders II. The general manager and technical director have revealed their challenge to get the game running on the Wii U hardware in time for E3, but was later scrapped by Nintendo for uncertain reasons.
They also describe the ease of developing for the system and getting the game to run on the controller is simple. Ideas for the Wii U's unique controller are already being discussed during the video, as well, with no firm plans on what they'll utilize just yet.
