The year is 1967 and The Beatles have gone missing! Through meticulous research, we have uncovered that they're hiding in a yellow submarine somewhere in the vast ocean. Your mission is to navigate your probe through the waters to locate the elusive submarine.

Every few seconds, one of The Beatles will peek out briefly, giving you a clue to their location. Your probe scans in a circular radius — if the submarine is detected, you'll get a compass direction hint (N, NE, E, ...).

Use arrow keys (Player 1) or WASD (Player 2) to move. Adjust the scan radius with the slider to narrow your search. Find them within the win distance to complete your mission!
