What FISH is
FISH is a 2D platformer run and gun shooter where you play as an armed fish fighting through multiple levels. You move through each stage killing enemies and taking on a boss at the end. The artstyle is deliberately weird and stylized, with a lot of meme-flavored humor baked into the presentation. Expect a game that plays like a classic run and gun but looks like nothing else on the shelf. The store text also flags sexual content, so keep that in mind if you're playing around people who'd rather not see it.
How a group plays it together
The game is listed as singleplayer, so one person is the one holding the gun. The way a group gets in on it is Remote Play Together, which lets friends join your session over the internet and share your screen. That means your friends can watch along, shout advice, and take a turn if you hand over control, all without needing their own copy. It works well for a game like this, where the fun is partly playing and partly heckling the person currently dying to a boss.
What to know before starting
FISH is in Early Access, so it's still being worked on and things can change between sessions. The structure is linear: clear a level, beat the boss, collect money, then spend that money in the next level on better firearms. Gun customization is part of the loop, so the weapons you buy and tweak carry the run forward rather than being picked up off the ground. Difficulty comes from the shooting and the bosses rather than from exploration choices, since the levels follow a set path. If your group wants something short, silly, and easy to jump into for a session, this fits that slot.
