It's fun as a side mode, but it doesn't really live up to the Octo Expansion or do enough to justify the $25 expansion pass for Splatoon 3. The enemy variety is also super disappointing considering this is a roguelike mode that needs to be beaten at least 15 times if you want to get everything out of it. I'd need to sit down and count the enemies from the other modes but it kind of felt like the base game's story had more enemy types, and even Salmon Run has all the bosses it throws at you on top of the horde, while here you just have several varieties of fish that swim at you and a handful of enemies that actually have attacks.

Side Order is a fantastic name for it, though.
