The apocalyptic technological singularity has dawned. Narrowly escaping the mass outbreak of genocidal robots, a lone sailor boards his craft and sets sail to the only place where he is strong and machine is weak: the water. Through a first and third-person view, the sailor fights off hordes of mechanical pirates, loots their ships, acquires new materials, and crafts water-ammo-based military infrastructure. In the midst of battles, the sailor steers his rig around storms and towards nearby ports to pick up survivors, train soldiers, and develop a new civilization on the sea. His boat -- and eventually his armada of vessels -- soon becomes humanity’s last hope.
