BETTER TOGETHER
Two phones.
One crew.
Fight the same battle. In Signal Rescue, Radar sees the caller’s beacon and Navigation sees the harbor manifest. Talk, compare and decide together. Roles swap at the next check.
Create a room
Choose a mission on the Battle screen, then invite one friend. No account is needed to play.
Join your friend
Connecting to your fleet…
Share invitations only with people you trust. Rooms are for two players. Each player uses their own verified equipment; a friend never needs to pay to join. Co-op is casual and host-simulated, not a certified competition. Keep both screens open during a mission.

Every mission can bring you closer. Earn stars, complete your harbor and make it your own. No construction timers.

Progress & accessibility
Mix mode is designed to let Spotify, Apple Music or other background audio keep playing while BOOOM44 effects stay quieter.
Game sound uses your media volume. On supported iPhones, Silent mode can stay on. Muting game sound here still turns all effects off.
Progress files never grant paid items. Paid items are verified by the server. Keep your own export as a backup.
