Great trailer, but the game is much more fun than the trailer makes it look. It's battle royale on a pirate ship with 4-5 teams of 4. You can occasionally run into people while looting an island, but most of the combat occurs at sea. Along with the obvious weapons and ammo, you'll find ship upgrades while looting islands. There are spots on every island that allow you to teleport to your ship. If you die, you'll re-spawn with your previous weapons as long as your ship is floating, but you'll drop your inventory. You need to sink their ship. It's fast-paced cannon blasting, hole repairing, water pumping, and the classic t-bone to board the enemy's ship and get close and personal. Pummel them with shovels, pull the cork, steal their wood and ammo, and make your getaway before they re-spawn. All this is done without voice or text chat. There are some preset commands, but mostly everybody just does whatever they can to win.
There are some issues with matchmaking though. Sometimes I have to restart the game for it to find a match and sometimes you end up on a 2-3 person team which is a huge disadvantage. Other than that, the game runs smoothly.
