'Assassin's Creed IV: Black Flag' trailer leaked

Ubisoft is having an incredibly hard time keeping anything Assassin's Creed IV-related a secret.

The leaked trailer reveals the game's release date and a particular pre-order bonus. The trailer also states that Black Flag will be coming to "next-gen" systems as well.

The trailer points to October 29th being the game's release date, which jives with past Assassin's Creed titles.
