Steam Next Fest runs Oct 19–26, 2026, and it is full of free co-op demos built for screaming at your friends. These are the chaotic co-op ("friendslop") demos worth downloading this week, checked on October 19, 2026. Dear Passengers fans: the Dear Passengers demo isn't out yet, so start with #1.
Full disclosure: we made #1. The rest are new demos we picked from Steam's online co-op list.
Feed your passengers. Or they'll eat each other. Run an airline with cannibal chickens, radioactive passengers and screaming babies you can throw off the plane. Fly, serve, repair and try to land. Play solo or with up to five friends.
It's the other "worst airline in the sky" co-op. Both games were revealed on the same day, July 14, 2026, by two different teams. You can play this one now.
Run a barely-stable nuclear reactor with friends: fix broken systems, manage radiation and stop the meltdown. Physics chaos, very close in spirit to an airline gone wrong.
A gang of raccoons on ridiculous heist missions, stealing everything that isn't nailed down while an exterminator hunts you.
Co-op puzzle rooms full of giant buttons. Every wrong press drags the facility further into chaos, and someone always presses it.
Tiny skeletons raid medieval castles, dodge guards and lose limbs along the way. Physics objects and plenty of falling apart.
A warehouse job that goes wrong in co-op: take orders, find parts, pack products and handle incidents against the clock.
You just got fired and your badge works for 15 more minutes. Prank and sabotage your manager as a team before time runs out.
Run a cult disguised as a restaurant with friends: sacrifice customers, perform rituals and summon an ancient god between orders.
A competitive party game with combat, tag and hide-and-seek modes. Less co-op, more chaos with a big group.
