Fartnership

Fartnership is a silly low-poly 3D river game where the whole crew stands on the rim of one round raft and the only engine is gas. Every fart shoves the raft away from whoever let it rip, so to go forward someone has to walk to the back and push. With four people on one keyboard it quickly turns into shouting about who should move where.

Timing your toots

Farting at the same moment as a crewmate gives the raft a much stronger push, so crews often count down together before a gap. Each player has a gas meter that drains while you fart and refills when you stop. Empty it and you're locked out for a moment. You can also hold it in: pressure builds up, and letting go just before the peak gives a big kick. Wait too long and it slips out on its own.

Food on the course helps everyone on board. Beans top up your gas, soda turns you into a stream of rapid toots, chili sets your farts on fire, cabbage brings a MEGA fart, and broccoli leaves stink clouds that send rival rafts spinning. Hit spikes, though, and the raft pops and goes back to the last checkpoint.

What happens if I fall off the raft?

You land in the water and swim back to the raft. A crewmate can knock you off with a butt bump, so watch your step on the rim.

How do I steer in a straight line?

Stand on the opposite side from where you want to go. If you're alone at the back, the raft goes forward. Players on the sides push it left or right.

Can I change my character?

Yes. Pick an animal like a hippo, capybara, frog or pig, dress it in briefs, a kilt, a diaper or a tutu, and choose or record your own fart sound in the Fart Lab.
