Splatoon 2 is getting a huge version 3.0 update in late April 2018, according to a recent Nintendo Direct. The update brings over 100 pieces of gear to the shop along with the Piranha Pit and Camp Triggerfish maps returning from the first Splatoon and a new map based on a theme park. Rank X will also come to the game which is one rank higher than S+. Callie will appear in Octo Canyon if you meet certain conditions.
The game will gets a single player expansion in the summer where an octoling called Agent 8 explores over 80 test facilities that dive into the lore of the game. After playing through all the levels, you’ll get to play as octolings in the game. The expansion is also available for pre order from the Nintendo eShop for $19.99 and doing so will grant you the Octo Headgear and Clothes for use in Splatoon 2.
