A new trailer for Assassin's Creed: Unity takes to the highest tops of buildings to show off customization and co-op play — features creative director Alex Amancio calls "the most requested features from Assassin's Creed fans."

In the new gameplay, Amancio explains that players will be able to customise their assassin's skills and look, which they can then take online for co-op missions with friends. Arno, depending on the player's choices, can change his navigation and stealth abilities, which allows players to build up specific talents and experience.

Arno's outfits will also impact on how easily he can blend in or move. Low-profile hoods, for example, will give him an advantage, and wearing heavy armor will make him stronger but slower. Check out the video below for a more in-depth look at the game's new features.

Assassin's Creed: Unity will be launching November 13th for PC, PlayStation 4 and Xbox One. A last-gen version, Assassin's Creed: Rogue, will be launching for PlayStation 3 and Xbox 360 come the same day.
