the flooded world

you are a simple robot (or person) named Charlie, you are on a small military boat with your mutated hamster (the hamster has upgraded everything, he has become smarter, stronger, tougher, more resilient, and other characteristics), 2 friends (who are as fucked up as you are) 4 construction drones and 1 cockroach (that's the team), the whole world was flooded except for small lands, billions of other ships are floating on the sea, upgrade your ship by fighting with others and taking valuable blueprints and equipment from ships (Ultra weapons, hangars for construction drones, towers, all sorts of 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
