A physics-based co-op party game where 2-4 players steer one shared raft - entirely with fart power.
Fart Together is GamesMrkt's debut Steam release: a physics-based obstacle course game where two to four players share a single raft and drive it by farting. Direction, throttle and timing all come from the players at once, so the raft never does what one person wants. This wiki covers the shared-raft physics, the course design language, the Team Race versus mode, and how to actually coordinate with the people you are stuck on a raft with.
2-4 players share a single raft. Your direction, power and timing all apply to the same hull, so nobody steers alone and nobody gets to complain alone.
There is no engine. Gas is the only source of thrust, which means acceleration, braking and turning all have to be negotiated out loud.
Up to 8 players split into two teams race their own rafts through the same course. Same physics, double the chaos.
The playable cast includes hippos. The studio genuinely tested hippo farts during development. Expect the joke to be load-bearing.
Fart Together is a physics-based co-op obstacle course game by GamesMrkt, an independent studio that has been developing games since 2018 and is releasing its first Steam title with this one. It launches into Steam Early Access on October 29, 2026 and is listed as Free to Play on the store page.
The premise is simple to state and genuinely hard to execute: two to four players sit on one raft, and the raft moves because everyone farts at it. There is no engine and no rudder in the traditional sense. Every input a player makes contributes force to the same shared hull - so the boat's movement is the compounded sum of what everyone did in the last second, not what anyone intended.
The studio's own framing is the design brief in one line: "The secret isn't farting harder. It's farting together at the right time." That distinction matters, and it is the entire difference between a group that clears a course and a group that spends ten minutes arguing. The developers also openly admit the raft does not simulate real raft physics - and that this looseness is deliberate, since arguing about why the boat suddenly flew sideways is part of the comedy.
The demo proved the appeal fast: it exceeded 3,500 concurrent players and picked up more than 20,000 wishlists within roughly a week, and ranked among the twenty most-played Steam Next Fest demos. The Early Access roadmap responds directly to that feedback with more playable characters, more customization, longer and harder courses, and new modes.
This is the single most important thing to understand about Fart Together. When two players push in opposite directions, their inputs do not cancel out into a neutral middle. They compound, and the raft lurches or spins. That is why a raft can be moving perfectly fine and then suddenly rotate 90 degrees because two people both decided to "help" at the same moment.
Every player contributes three things to the raft's state:
Because these are continuous physical contributions rather than commands, the raft does what the group's net force says. The fastest way to describe the control scheme is that you are not steering a boat - you are applying force to a boat that other people are also applying force to, and physics resolves the argument.
The community's practical advice converges on three patterns, one per obstacle type:
