Finish all three storms in the browser to submit one score. Your public name is chosen inside the game; practice runs and incomplete shelters stay off the board.

Scores are for fun and can change during the beta. No account or private information is required.

Build for 45 seconds, then protect the gold shelter through a 20-second debris storm. Survive all three rounds—or learn at your own pace in untimed building practice.

Solo: click to build, right-click to reclaim, 1–3 to choose materials, Z to undo. Green placement previews are valid; red previews explain what needs changing. Press Esc or Pause to pause. On a controller, choose INPUT: CONTROLLER in the menu, use the stick or D-pad to move, A to build/select, B to reclaim/back, and Y to change material.

Music starts after your first click or keypress if your browser blocks autoplay. Adjust Music and Effects independently in the main menu. Online PvP uses one browser per player: three rounds, independent supplies, identical storms, timed shields, and attacks. Online co-op uses the same room-code flow; both players select Ready. If the free server sleeps, use Reconnect Last Room after it wakes.
