Splatoon's the last to explore the GamePad, and it does so the most comprehensively. Somewhat controversially it uses gyro controls for aiming - although they're slick, well-implemented gyro controls - as well as making use of the touchscreen and the space between the GamePad and the television. You're in two teams of four, the objective simply being to paint as much of the map in your own colour as possible. It's a messy joy: the sound of paint slopping around surfaces is perfectly pitched, the feel of the weapons is wonderfully weighted.
It's very smart, too - if you've painted an area, you can turn into a squid and dive in, swiftly stalking your own territory. As a squid, you can also leap instantly to your team-mates by pointing to an icon that hovers over them in the mini-map displayed on the GamePad. At a show dominated, as ever, by straight-faced shooters looking for a point of distinction, it's incredible that Nintendo's created the most dynamic and quite simply joyous one on the show floor.
