Echo Divers

Light the dark with sound.

You can only see what your sonar wave touches. Dive into a pitch-black cave alone or with up to 3 friends, ping your sonar to reveal the walls, recover the data cores and bring everyone back to base — but every sound tells the predators exactly where you are.

Co-op for 1–4 players (room code / random match / public rooms)

Throw decoy buoys to lure predators away from your friends

Locked vaults, warps, air pockets and a shared pool of lives

Daily Challenge: the same map for everyone, every day, with solo and team rankings
