Ubisoft is getting back to what it does best: Pirate Games.
Clearly, after the love for Black Flag it wanted to make more pirate games but the needs of Assassin's Creed series has moved on from being able to focus on that setting soooo... whole new series.
The trailer looks awesome but it is all cinematic so doesn't really give away what the game will be like to play, only that it features much swashbuckling action.
Thankfully there's also a pretty in-depth in-game trailer, too. Unlike Assassin's Creed, Skull & Bones will be a multiplayer game. Look at it in action here:
It's a 5v5 multiplayer game, with each player commanding a separate ship. Much like the different classes in Rainbow Six Siege, you'll want to have a spread of ship types under your command in Skull & Bones to overtake the other team.
It looks pretty bloody brilliant and bizarre.
