Assassin's Creed Unity will be the first installment in the series to feature four-player co-op, if a new rumour is true.
Described as a four-player "narrative" mode, the feature will reportedly be demonstrated during one of two Assassin's Creed: Unity trailers, with the other focusing on the game's single-player mode.
Ubisoft will deliver its annual E3 press briefing on June 9, the publisher confirmed last week.
Unity was officially announced on March 22 following the appearance of leaked promotional material. It will release for PS4, Xbox One and PC this "holiday season".
Meanwhile, it's rumoured that Ubisoft will also publish a second Assassin's Creed game this year in the form of Comet, which will release for last-gen consoles.
The Assassin's Creed series has sold about 73 million copies, making it Ubisoft's best-selling series by 25 million units, the publisher announced today.
