Nintendo has announced a new, worldwide Splatfest for Splatoon 2 to celebrate the game's one year anniversary - and this time it's a big one.

Yes, players must choose between Team Squid or Team Octopus in an ultimate showdown between the two primary playable sea-dwellers. Will you be sticking with the squids, who have been your trusty companions from day one, or will you be siding with the fresh new octopus-based Octolings?

Interestingly, if you choose Team Squid you will be playing as a regular Inkling, but if you choose Team Octopus you'll play as an Octoling - even if you haven't purchased the Splatoon 2: Octo Expansion.

The Splatfest will take place on 21st July (the day that Splatoon 2 was released last year) to 22nd July, with team registration starting much sooner. As mentioned above, this is a worldwide Splatfest so all regions will be taking part in the same event.

The question is obvious - which team will you be on? Let us know in the comments below.
