I like Splatoon 3's Specials weapons :), even though some suck, some are Great, and some hurt your soul for being on a main weapon that doesn't feel right with it... Looking at you Reef-lux 450 Deco 👀
DLC (downloadable content) includes any content that wasn't part of the base game. And since some of these weapons weren't in the game at the time of its release, they are DLCs ;)
