How many players for fast-food Simulator?

There is coop in it, at least thats what said in steam

Bro, you can roll solo or squad up with up to 4 homies in Fast-Food Simulator. It’s way more lit when the gang’s all there—like, one dude’s burning burgers, another’s losing it over the ice cream machine being down again. Total chaos, but hilarious. Running it solo’s cool too if you’re tryna prove you’re the top chef or whatever
