Ubisoft is marketing Assassin's Creed Unity as a game that's best played cooperatively with other players. Sure, new protagonist Arno may be formidable on his own, but some of the missions in Unity require teamwork and well coordinated movement. Co-op and character customization are the focus of a newly released trailer for the game, with Ubisoft claiming the latter is crucial to the overall co-op experience.

Players will be able to tweak and tailor the appearance of their assassin by upgrading their armor, weapons and basic outfit colors. One example given in the trailer explains the benefits of changing from one type of hood to another, lower-profile variant that allows you to blend in with the crowd more easily. This small shift increases the range of Eagle Vision, thereby making it easier to spot your target before making a move.

Additional changes extend to using different swords for combat or chest armor. Will you sacrifice speed for damage or more protection for stealth? Previous Assassin's Creed games have implemented equipment upgrades, but Unity appears to be taking a different, more focused approach to it.

This focus, or more depth, can be seen in the different play styles as well, which are also customizable. The variety of skills and abilities forgoes the need for a set number of classes. Melee, stealth, ranged and healing are the four main things a character can specialize in, before further modifying them to incorporate bits and pieces from the rest to form a unique play style. In theory, no two people will play exactly the same, and their abilities, equipment and so own will compliment each other, making up for the weaknesses found across the team.

Group abilities are another extension of this. One such skill, known as Communal Sense, shares Eagle Vision with all members of the team, while the Disguise ability will make everyone appear as regular, seemingly innocent civilians. Whether players will dive in and take full advantage of the character customization to better complete missions, or simply run in swords drawn, will be interesting to see. Over the years, the Assassin's Creed games have either made the stealth aspect a lengthy bore, where getting spotted once means restarting a checkpoint, or dismissed its importance and allow people to run in and murder everyone.

Judging by Unity's take on co-op, though, the series may be trying to blend the two. If you want to dress up as a real-life assassin, check out Musterbrand's Assassin's Creed Unity's clothing line.
