Krew.io is a great sea cannon shooting game that takes place in a 3D world. In Krew.io, you play online with people from all over the world. And the goal of the game Krew.io is to get the highest score or to be the last player left. You don't have to download anything or sign in. It's all free and quick.
This game is fun to play with friends or by yourself, because if you are good enough, you can destroy an entire fleet by yourself. Be careful, though, because there are also AIs roaming the seas, and they are in giant pirate ships that your team needs to work together to take down.
How to play
To be good at Krew.io, you'll need a lot of control practice. When I first took control, it felt strange to move my cannon around the boat to steer it, which obviously changed its position. If you shoot from there, you'll need to make changes before you attack. Teamwork is very important at sea, and a captain is only as strong as his crew. Keep in mind that there are intact captains for teams who will be randomly chosen and replaced when they die, according to I know of no benefit to you other than being able to give commands in chat.
Use the WASD keys to move your cannon around the boat. This will turn the boat in the direction you are going. Use the mouse to control the boat and aim your cannon.
