Nintendo has revealed several details and screens for the fat August due update for their Wii U exclusive TPS Splatoon.

The update will add new game modes, weapons, an increased level cap and more than 40 pieces of new gear. The new modes include Squad Battles and Private Battles:

In Squad Battle, players can participate in Ranked Battle rule sets with friends, rather than being teamed up with other players through a random selection. After a player creates a squad, friends can be recruited to form a team of two to four Inklings. Friends will always play together on the same team and battle against other squads at random.

In Private Battle, friends can splat it up in private, customisable matches. Two to eight friends can battle together by selecting their favourite map, mode and weapons. The number of participants ranges from 1v1 to 4v4, but teams don’t have to be even: if the host chooses, he or she can select a 1v4, 1v2, or any other combination of players.

We can see some of the new gear and game-play of the options in the new modes in the screenshots, which I've added below for your viewing pleasure. Nintendo also notes that this is far from last of the free content that will be released for Splatoon, which will continue to receive support throughout the year.
