If Nintendo's going to make a competitive online shooter, then darn it, they're going to do it their own way. Splatoon is an original game coming to Wii U where teams of four human-squid hybrids face off to cover the majority of the map with their squad's color.
As a human, you'll be able to cover the map with your color, but a match can't be won with one species, as people will trudge slowly through enemy ink. A squid can dive into their team's ink to cover large distances in short amounts of time. Regardless of what species you're playing as, you'll be able to keep an eye on the map and the paint progress via the Wii U Gamepad. While lagging behind a teammate is a commonplace problem in traditional shooters, the Gamepad offers a pretty simple, yet innovative solution; just tap on a teammate, and you'll blast across the map to meet them. We saw a few other weapons at play (a roller, and some sort of triangle mine), so we still have much to learn before Splattoon splatters on our Wii Us in 2015.
