Autobomb

The Autobomb is a sub weapon in Splatoon 2.

Description
Autobombs are comparable to s from Splatoon. Unlike the Seeker however, they do not leave a trail of ink and can freely change direction.

Once the Autobomb reaches a player or travels far enough without reaching the player, it will explode. If thrown and no enemies are in range, the Autobomb will automatically explode where it was thrown, similar to a.

Due to the fact that the Autobomb walks towards nearby opponents, it can be used to locate hiding enemies. The Autobomb is small, does not spread ink, and is able to walk in enemy ink unaffected, so it can sneak up on opponents more effectively than an Inkling can.

Trivia

 * It is also believed that the design is based on a jigsaw, a power tool commonly used in industry and construction.
