try using chute vent on water hazard.
this is just a list of games where you get ship battles.
Assassins creed black flag.
World of Warships.
Pirates of the Carribean online. (feels a bit like goio were you fight other ships and AI)
pirates of the burning sea. (this one looks promising.)
World of Warships - That is like WoT and WoWp, you play as a full machine yourself. I meant the specialities like in GoIO, and several ppl using the same ship. Also, it's about modern metal ships.
Pirates of the Carribean and pirates of the burning sea - these are just another MMORPG like World of Warcraft. Also these are 3rd person view...
Actually I really hope the game I wish for looks exactly like GoIO, but on the water and with larger crew... And maybe in a real history universe, not steampunk. As I saw from the answers, this game does not exist, yet I think it would have a GREAT potential!
You remember the Red Orchestra where several ppl use a tank? Driver, shooter, machinegunner, etc. the same can be accomplished on ships, and not in RPG style like Pirates of the Carribean, but the same GoIO style - fast 15-min fights.
Muse, it's your chance to use this niche while no-one made it (as I see it).
Thanks.
