Mobility

Weight is a game mechanic that matches the mobility stats of Inklings and Octolings with roughly how heavy their equipped weapon may be.

Weight classes are categories that main weapons belong to based on their weight.

Splatoon
The mechanic was not used extensively in Splatoon. At first, it was only applied to the Rainmaker, which reduces swim speed by 20% and reduces run speed by 60%. The mechanic was first applied to main weapons in Version of Splatoon.


 * Notably, the weapons under the heavyweight class have large metallic designs.

Splatoon 2
The weight mechanic was expanded in Splatoon 2 to affect run speed based on the main weapon equipped in addition to affecting swim speed. A new lightweight class was added to allow increases in mobility.
