Hunt a submarine you cannot see. Ping the dark, triangulate the echoes, and torpedo the spot you deduced.
OBJECTIVE
Blast the most hidden subs before the dive timer ends — the ghost is worth double.
HOW TO PLAY
1.
Your sub always drifts forward — hold left/right to steer, and it wraps around the edges
2.
Everything is invisible: ping to briefly reveal nearby subs' trails and which way they're heading
3.
Lead your target and fire your laser — the beam lingers, so any sub that crosses it is hit
4.
Enemy subs are big and slow (1 point); the ghost is small and fast (2 points)
5.
Most points when the timer ends wins
Every mode runs Deep Sonar with its own format and rules.
