Crimson Ocean

Naval bullet hell

Crimson Ocean is a PC bullet-hell action game about piloting a naval destroyer against an extraterrestrial industrial harvester in Earth’s deep ocean. The harvester isn’t trying to conquer humanity: it’s gathering raw materials and building a planetary operations hub. Its automated machinery classifies your ship as an obstruction and tries to crush, tow, and recycle it.

You steer through attacks and maritime hazards while fighting the machines sent to dispose of your destroyer. The enemy’s weapons are industrial equipment rather than conventional alien guns: heavy tugs ram your hull, dredge shredders tear through the water, and magnetic barges drag ships toward processing furnaces.
