Nintendo announced today during their E3 Nintendo Direct that Splatoon, a multiplayer focused shooter, would arrive on Wii U later this year.
Splatoon encourages players to paint their environment in order to win the match, with GamePad tilt controls and a persistent map on the handheld screen. The object of the game is to defend your territory while aggressively painting the enemy's area.
Nintendo doesn't make a lot of shooters, but this one seems to address quite a few stale mechanics. You can eliminate enemies with your own paint and paint grenades, but you can also swim as a squid through your own paint to get to other parts of the map very quickly. Trying to walk through enemy paint will slow your character down drastically.
We'll have impressions of Splatoon later.
