This DLC for Splatoon 2 adds a single-player story mode with 80 challenging levels. The plot revolves around Agent 8, an Octoling who has fallen into a shady testing facility deep underground and lost their memories. With the help of characters both old and new, they must complete the tests in order to regain their memories and find a way to the surface. The new levels require the player to use advanced techniques and demonstrate expertise with a variety of weapons.
Upon purchase of this add-on, players will also receive two exclusive pieces of gear for their multiplayer avatar. In addition, clearing the new story will unlock Octolings for use in multiplayer modes.
