Clam Blitz

Clam Blitz is one of the four Ranked Battle modes in Splatoon 2, alongside Splat Zones, Rainmaker, and Tower Control. Clam Blitz is the first ranked mode introduced in Splatoon 2 that wasn’t in Splatoon.

History
Clam Blitz was announced on November 21, 2017 when Nintendo released a video showing the updates for the coming weeks.

Gameplay
The objective of Clam Blitz is to pick up clams, which are scattered around the stage, and deposit them into the goal near the opposing team's base. Once a player picks up ten clams, it transforms into a power clam, which is used to destroy the barrier of the goal. The power clam can be thrown from player to player, however, if the player receiving the power clam is holding any smaller clams, they will be dropped. Players can also splat opposing players to make them drop their clams, which the player can then take them for themselves.

Trivia

 * The power clam resembles an American football.
