Stop The Tsunami Players & Co-op Hub
Roles, controls, and team habits that keep the town dry when the wave hits.
Stop The Tsunami! is built for shared work. Dig sand, pile walls, carve trenches, pack them hard, then press START ROUND and survive for coins. In multiplayer you share one coin wallet and every machine, so player skill is less about a personal loadout and more about roles, timing, and etiquette. This hub explains how to pick a job on the beach, how to choose Easy, Medium, or Hard without tilting the lobby, and where to go next for controls and deeper co-op tactics.
If you are brand new, skim Getting Started first, then return here to decide how you fit into a crew. Input details live on Controls. Full teamwork patterns live in Co-op Guide. Spend priorities sit in the Tier List Hub.
Core roles on the beach
Most successful lobbies settle into three overlapping roles.
Diggers open volume. Early on that means the toy spade and shovels; later it means bulldozer, skid steer, or excavator passes that clear sand so walls and trenches can form. Diggers should leave piles where packers can reach them, not scatter sand across the map for aesthetics.
Drivers and haulers specialize once heavier machines unlock. An excavator driver focuses late beach clear; a dump truck driver moves gravel, boulders, clay, and concrete to the wall line. Because machines are shared, call when you hop in and park where the next teammate can take over.
Packers and patchers turn loose piles into a real defense. Packing is mandatory鈥攕oft walls fail even if the silhouette looks tall. During the wave, patchers repair breaches while others keep haul routes open. In small lobbies one person may rotate through all three roles; in fuller servers, specialize.
Nobody 鈥渙wns鈥?the START ROUND button alone. The player who starts the round should confirm the crest is packed, flanks are covered, and haulers are not mid-trip with critical materials still unloaded.
Co-op etiquette that saves runs
Shared wallets make impulse buys a team problem. Announce big machine purchases before you drain coins the packers needed for the next material unlock. Do not camp the only excavator while four people wait with shovels. If you finish a dig pass, hop out and help pack instead of emoting on the crest.
Communication beats clutter. Short calls work: 鈥減acking center,鈥?鈥渂oulders on left flank,鈥?鈥渘eed dump truck,鈥?鈥渞eady to start.鈥?Avoid starting rounds while someone is still sculpting clay on the impact face. After a fail, spend Beach Club Rewind thoughtfully if the group has it鈥攔ewind is free value from the Beach Club group, not an excuse to ignore packing mistakes.
Daily Spin and daily rewards help the shared economy. Claim them, then funnel value into the bottleneck the whole lobby feels: dig speed, haul, or better fill.
Choosing Easy, Medium, or Hard
Easy is the classroom. Learn dig-build-pack, survive for coins, and unlock early shovels without punishing every soft edge. New players and mixed-skill friends should stay here until START ROUND feels intentional.
Medium is the proving ground. Waves punish unfinished packing and thin flanks. Bring gravel and boulders into the plan, and expect crews to need clearer roles.
Hard assumes you already move like a team. Monster waves on a widened beach demand clay, concrete, and S-tier machine support. Jumping into Hard with a toy-spade lobby and no packer usually wastes everyone鈥檚 time鈥攙ote difficulty to match the weakest prepared player, then climb together.
Difficulty does not change the fact list: creator jzf25 designed shared machines and a shared wallet on purpose. Your 鈥渂uild鈥?is the wall, not a private gear score.
How to use this hub
- Learn inputs on Controls for PC and mobile.
- Align roles with Co-op Guide.
- Onboard friends via Getting Started.
- Spend coins using the Tier List Hub instead of random shop clicks.
Solo players still benefit from role thinking: alternate digger and packer hats in one body, and never press START ROUND on an unpacked pile. When friends join, hand off the hat you are worst at and keep the one you execute cleanly.

What roles matter most in Stop The Tsunami co-op?
Diggers clear volume, drivers haul and run heavy machines, and packers seal walls then patch mid-wave. Share the wallet and rotate if the lobby is small.

Which difficulty should new groups pick?
Start on Easy to learn packing, move to Medium when clears feel stable, and save Hard for crews ready for clay, concrete, and late machines.

No. Co-op uses a shared coin wallet and shared machines, so purchases and digs affect the whole team.
