What we mean by a co-op physics game
A lot of games have physics. In the games on this list, the physics is the game: you can’t predict exactly what will happen, and the funniest and most memorable moments come from that. We sorted them into three kinds, because they suit different groups:
- Wobbly bodies and ragdolls: your own character is the unpredictable part.
- Physics you carry or climb: objects, ropes and ledges that react to everyone in the group.
- Driving physics: weight, grip and momentum decide where your vehicle ends up.
This isn’t a ranking. We don’t have data that says one game is better than another, so we tell you what each one does well and who it suits. Player counts come from the games’ Steam store pages, checked in October 2026; they can change with updates, so check the store page before you plan a big night. Full disclosure: we make one of the games on this list.
Wobbly bodies and ragdolls
Human: Fall Flat
A light-hearted physics platformer set in floating dreamscapes. You play as Bob, a soft, floppy character who grabs, climbs and carries things with two arms you control separately. The store page lists solo play and up to 8 players online.
Why it’s here: It’s the classic: easy to pick up, funny to watch and gentle enough for mixed groups, including friends who don’t usually play games.
Gang Beasts
A party game with gelatinous characters, slapstick fights and hazardous stages. It’s about throwing each other off things rather than working together.
Why it’s here: It isn’t strictly co-op, but it’s one of the purest ragdoll-physics party games, and a good warm-up for a group night.
Totally Reliable Delivery Service
A ragdoll physics simulation about terrible delivery couriers. You work together with odd machinery, gadgets and vehicles to get packages to their destination, more or less in one piece.
Why it’s here: It’s the silliest game on the list, with vehicles that are as unreliable as your body. Good when your group wants chaos without stakes.
Wobbly Life
A colourful open-world physics sandbox with jobs, minigames and story missions. You earn money in the world to spend on clothes, vehicles and houses.
Why it’s here: It’s the most relaxed option: no mountain, no pressure, just a physics world to mess around in together.
Physics you carry or climb
R.E.P.O.
An online co-op horror game in which you find valuable, fully physics-based objects and haul them to extraction without breaking them. It’s in Early Access on Steam.
Why it’s here: Carrying a fragile object through a dark corridor with five friends is physics comedy and tension at the same time.
PEAK
A co-op climbing game in which a group of lost scouts must climb the mountain in the middle of an island to get rescued. The slightest mistake can be fatal, and helping each other up is the core of the game.
Why it’s here: It’s the best-known co-op climb right now. The physics is in the climbing: grabbing, hauling and falling together.
Chained Together
Up to four players chained together climb up out of hell. Every jump pulls on everyone else, so one bad move can bring the whole group down.
Why it’s here: The chain turns physics into a group decision, and it made "co-op climb" one of the big genres of the last few years.
Bread & Fred
Two penguins tied together by a rope try to reach a snowy summit. You time jumps, cling to walls and swing across gaps, and if you slip you can tumble a long way back down.
Why it’s here: It’s the best physics co-op game for exactly two people.
Driving physics
Drive UP: Together
A co-op climbing game built on a proper driving simulation. Up to eight friends drive the same route up one mountain: planks barely wider than your axles, near-vertical ramps and the insides of giant pipes. Every meter is earned: one slip can cost you a lot of hard-won height.
Every car is a solid object, so the same controls let you be the bridge (park across a gap so a friend drives over you), the engine (push someone over a ledge no single car can clear) or the problem (tap a bumper one wheel from the summit).
Why it’s here: It’s the driving-physics pick for groups. Weight shifts forward when you brake, the back end steps out if you get greedy with the throttle, and tires let go of a steel ramp at the worst moment. With up to eight solid cars on the same narrow route, the other players are part of the course.
BeamNG.drive
A soft-body physics vehicle simulator: cars bend, crumple and break in a way few other games attempt. It’s in Early Access on Steam.
Why it’s here: It’s the reference for vehicle physics, but it’s a sandbox rather than a co-op game with a shared goal. Check its store page for the current multiplayer options.

How to pick
Two of you? Bread & Fred is built for exactly that. Three or four? PEAK and Chained Together are the obvious picks, and R.E.P.O. stretches to six. Five to eight? Most physics co-op games stop at four, which is why Human: Fall Flat and Drive UP: Together come up so often for big groups. Want zero stakes? Totally Reliable Delivery Service or Wobbly Life. Want every fall to hurt? Read our rage games guide.
Real driving physics, up to 8 friends
Drive UP: Together is out now in Steam Early Access. The free demo is the quickest way to find out who in your group is the bridge and who is the problem.
FAQ
What is a co-op physics game?
A game you play together where physics decides what happens: wobbly characters, objects you have to carry, ropes that tie you together, or vehicles with real weight and grip. The fun comes from moments nobody planned.
What are good co-op physics games for 8 players?
Human: Fall Flat lists up to 8 players online on its store page, and Drive UP: Together supports 1–8 players in online lobbies. Most other games on this list are built for smaller groups.
Is there a co-op game with real driving physics?
Yes. Drive UP: Together is a co-op climbing game built on a proper driving simulation: up to 8 friends drive the same route up a mountain, and every car is a solid object you can push, bridge or bump.
What ragdoll games can I play with friends?
Human: Fall Flat, Gang Beasts, Totally Reliable Delivery Service and Wobbly Life are all built around floppy, physics-driven characters and support playing with friends.
Can I try Drive UP: Together for free?
There’s a free demo on Steam, so your group can try the climb before deciding.
