SHORE makes the floor you are standing on the co-op problem

SHORE puts one to four people on a raft in the middle of the ocean and asks them to get home. The verbs are small and physical: paddle, and paddle in time with everybody else; move around the deck; grab whoever has gone over the side and haul them back; find food before hunger does the job the sharks were going to. None of that is unusual on its own. What is unusual is that the raft underneath all of it is fully simulated.

That one decision changes what every other verb means. Every wave tilts the deck. Every shift in weight changes the balance, so four players crowding the same corner to look at something is a mistake with a consequence attached. Currents push the raft off the heading the group agreed on. Standing still is a position rather than a neutral state, and where you put your body is information the other three need.

It also makes disasters legible. When a simulated raft goes over, nobody has to explain what happened — everyone watched the weight move. That is the difference between a co-op failure that starts an argument and one that starts laughing, and the developer’s own pitch leans on it: your friends are too heavy, and throwing one of them overboard is something the physics will cheerfully allow.

Around that sits the survival game. Hunger is a clock. The route home runs through biomes that each bring their own hazards — towering icebergs, sharks, whirlpools, things further down — and past abandoned islands, drifting wreckage and sinking ships that are worth stopping at and dangerous to stop at. Getting lost is easy, which is the honest way to describe a game whose map is water.

How Overcooked’s kitchens force you to communicate is the closest argument to what SHORE is attempting. The essay’s point is that Overcooked never manufactures teamwork by handing players different powers or different information — everyone has the same tools, and the kitchen itself creates the problem. SHORE hands everyone the same paddle and lets the raft create the problem. That is the harder version of the trick, and it ages better, because the pressure comes from a space that keeps moving instead of from a job list you eventually memorise.

The Rise of the Systemic Game explains why full simulation is worth the trouble it causes. Systemic games get their power from objects, characters and environments that can act on each other, producing plans and accidents no designer wrote down. A raft with real buoyancy, four bodies with real mass and a sea with real waves is a small systemic engine, and the best stories it tells are ones nobody had to author. The bill comes due in control: the same system that produces the great moment produces the unrecoverable mess, and finding that line is most of the work left.

The Two Types of Randomness in Game Design is the essay to hold the biomes against. Its distinction is whether the dice fall before the player decides or after. Roll the storm before the group picks a heading and the weather is a puzzle they get to read; roll it after they commit and it is a tax on having played. “No journey is ever the same” only pays off as the first kind, and an ocean is an unusually good place to show a threat early, because you can see weather coming from a long way off.

SHORE is by Underdog, self-published, listed as coming soon for Windows with a Q4 2026 window, under Action, Adventure and Indie. It runs one to four players, solo or in online co-op, which is the right range for a game about weight distribution — three friends is enough to capsize something, and one player alone is a different game with the same physics.

The developer is building it in public and says devlog comments from a couple of thousand people have already shaped what is in it. That is worth knowing before forming an opinion on any feature list, because the list is still moving.

If the appeal is a whole team made responsible for one fragile object, Keep It Up! is the other one on this list — the team shares a single balloon and every room is built to make them drop it. SHORE swaps the balloon for the floor everyone is standing on, which is the same idea with nowhere to put your feet.
