Splatoon

Splatoon is a 2015 third-person shooter video game developed and published by Nintendo for the Wii U. The game centers around player-controlled Inklings—squid-like lifeforms that can transform between bipdeal humanoid and cephalopodic forms at will. The game centers on a variety of four-on-four online multiplayer game modes that sees Inklings use a variety of weapons that can produce and shoot ink while in their humanoid forms or tread and hide in surfaces covered in their own ink while in their cephalopodic forms. It also includes a dedicated single-player story campaign.

Splatoon was developed by a young group of employees at Nintendo's Entertainment Analysis & Development division, and originated from a competitive multiplayer ink-based territory control game, which was later expanded to include squid and the ability to swim through ink. The concept was created by lead programmer Shintaro Sato, who had previously worked on games in the Animal Crossing franchise.
