Sink or Swim is in the demo — plus fixes for the first shop
The free demo has a new opening mission, Sink or Swim . We've also changed the early route and shop controls after players got stuck there.
Try a build before the first shop
Choose a temporary weapon mutation: wider attacks, extra pierce and damage, or heavier hits at a slower pace. Then ride a current and dodge the Loan Shark's charge. The mutation lasts until the first workshop, where you choose your lasting upgrades.
Sink or Swim works solo and in local shared-screen co-op. It turns itself off after your first attempt, including an early exit. To replay it, switch Sink or Swim ON in the main menu before a new local run. Online expeditions keep their usual opening.
Getting past the early menus
- On the route screen, Dive now starts selected. Confirm it to begin after your crew is ready.
- If the shop has free upgrades waiting, Ready takes you to those choices. Choose and confirm them before readying up.
- Tutorial choices accept controller A, Space, Enter or a mouse click.
Full-game route planner. Confirm Dive after checking your crew and destination.
Steam online co-op has now been confirmed in hands-on playtests. Friends need matching editions and updates: demo and full-game lobbies are separate. We're still gathering reports about smoothness and synchronization.
Try the updated free demo. The full game launches October 19. Gameplay and screenshots are on our website.
Still stuck? Tell us the screen, your controller or keyboard, and whether you're playing solo, locally or online. Include the title-screen build number if you can.
