Affordable Space Adventures is a unique recent release on multiple fronts - it's an Indie game that's also a Wii U exclusive, while it takes advantage of the Wii U GamePad's capabilities for dual-screen play. We were rather impressed and gave it a strong recommendation in our Affordable Space Adventures review.
Although it's been available since early April, there may still be plenty of Wii U owners unsure of its local co-op charms. With that in mind Nintendo of Europe has produced a video in which an NoE employee is joined by a member of the KnapNok team and Nifflas, the latter being the creative force behind a game. They show off three-player co-op, with some slick cutaways to the GamePad screen to show how the game works.
It's certainly worth checking out if you want to know more about this release.
