Keep the Strait of Hormuz open. Every 10 convoys the situation escalates.
1Ships sail on their own along the magenta lanes. You protect them.
2Red triangles are mainland ports (boats, boarding teams, missiles). Red diamonds are island bases (drones, submarines, underwater drones, mines). The pulsing ones attack next.
3Place escorts from the dock at the bottom left. They fire on their own. Tap the water to move your destroyer (white, with a gold marker above it).
4Every ship lost lowers Confidence; clean convoys raise it again. At 0% the strait is in crisis: convoys pay half until you win it back. The game never ends: play as long as you like.
