The extra in-game bonus content for Ubisoft's upcoming titles, Assassin's Creed 4: Black Flag and Watch Dogs, is said to stay as a Sony PlayStation exclusive for six months.

The timed-exclusive content includes game play of 60 minutes for both the titles, as promised in the new video by PlayStation.

It is speculated that Ubisoft could ignore the 60 minute game play on Microsoft Xbox, Nintendo Wii U and PC platforms after the completion of 6 months.

The assumption is said to be based on the previous steps taken by the publisher where it ignored the PS3-exclusive Benedict Arnold missions of Assassin's Creed 3 on other platforms, reports Shacknews.

The bonus 60 minute game play is said to arrive with three missions and will star Aveline, the chief character from Assassin's Creed Liberation version, according to CVG. The bonus content will be available for both Sony PS3 and PS4 console versions of the title.

In addition to this, another video has surfaced online, which gives a round-up on what the gamers can expect to see in Assassin's Creed 4: Black Flag.

The nine minute long video, titled "Assassin's Creed 4 101 Trailer" gives a short description of the in-game story, naval game play, exotic locations, pirate's life, under water features, animal kills and upgrades on land and in-game stealth and weapons.

The video acts as a brief guide for those who are yet to catch-up with the fourth version of the game. The trailer can be viewed below:
