Splatoon is primarily a team-based third-person shooter which is playable by up to eight players in 4-vs-4 matches although the game also features a single-player campaign. Players control characters called Inklings wich can change between human form and squid form. Transforming into a squid allows players to swim through ink of their own color even up walls and through grates hiding from the enemy and replenishing their ink supply in the process.
