the flooded world

You are a simple robot (or human) named Charlie. You are on a small military boat along with your mutated hamster (the hamster has been fully upgraded—smarter, stronger, tougher, more resilient, and other enhanced stats), 2 friends (who are just as chaotic/unhinged as you are), 4 construction drones, and 1 cockroach (that's the team). The entire world has been flooded, except for a few small patches of land. Billions of other ships float across the sea. Upgrade your ship by fighting others and looting valuable blueprints and equipment from their decks (Ultra-weapons, drone hangars, turrets, various factories, invisibility fields, and much more).

Transform your ship from a tiny boat into a giant floating city with the best equipment and become the King of the Seas!

this is the distant future, the whole world was flooded because of global warming, the surviving people and robots had to live on ships, you managed to take a small military missile boat, fight with other ships, take equipment from them and build your fleet, become the king of the seas
the world is at war between three coalitions
