Run Speed Up

Run Speed Up is an ability in Splatoon and Splatoon 2.

Run Speed Up improves movement speed while running and while firing the weapon. It also affects movement speed while using the Inkjet. It does not affect rolling speed with roller-type weapons, or jump length. Gear made by Rockenberg has a 5× chance of rolling this ability.

This ability is useful when rushing objectives in Ranked Battles during the opening moments of a match. It also increases survivability as the player will be more difficult to hit when strafing in a firefight.
