Up to 8 friends must try to survive!

You and up to seven friends are washed up on an island with a nail gun and no plan. Chop it down, drag it back, and weld a raft out of planks, barrels, doors, bathtubs and one inexplicable piano. Then the flood arrives, the island goes under, and whatever you nailed together is the only thing between you and the sea.

Crazy contraptions

Stuck on an island, what do you do? You pick something up, you hold it where you want it, you nail it. Bam. Welded parts fuse into one rigid hull, so a raft lists, rolls and rights itself according to what you actually bolted on and where.

Everything out there wants your boat

Fish are weapons

Cast anywhere there's water. Sword fish? Grappling hook, a rocket launcher, a leaf blower, an electric eel, an ink cloud, a boomerang, or an ocarina nobody asked for.

Between runs

A home island with a fisherman selling oars and rods, a shipwright selling boat gadgets, a wise man selling buffs you'll misuse, a fishmonger buying your catch, and a slot machine that has never once been a good idea. Photograph a raft you're proud of, save it as a blueprint, and rebuild it next run — or hand the code to a friend and let them build yours.

Bring people

• 1-8 players — drop-in Steam co-op via invite, join code, or the public games browser. Sweet spot is 2-4.

• Proximity voice chat — hold to talk, and you get quieter as you drift away. Go under and you get muffled before you go silent.

• 18 playable characters — a shark, a donut, a potato, a banana, a hot dog, a zombie clerk, and twelve more.

• Die and stick around — ghost your crewmates, watch the raft fall apart without you, and get revived if anyone bothers.

Every run is different

How long will you survive the floods?
