Concept work for "Assassin's Creed Duel", an unmade Ubisoft XBLA/PSN 2.5D fighter

...

 

I would buy this just to beat the crap out of Altair with Rayman xD

In all seriousness, this looked to be a pretty good concept, shame it wasn't made.

 

Are Ubisoft moving the way of Sony and making they're own Super Smash Bros?

Honestly, this seemed fairly terrible to me. Most of these fighting games are succesful because of a dynamic and diverse roster of characters that make them up. AC isn't like that by any means, you have cool Assassin protagonists, alright support cast, but no one stands out in terms of look or style.

I could see a roster of Ubisoft characters going at it, though. The mock up locked characters a the bottom are enough to warrant diverse looks and styles that might keep it interesting.
Imagine adding Aiden Pierce for WATCH_DOGS, Vaas form Far Cry 3, a few more lesser known titles' characters, and then we'd have a decent line up of characters to me.

Maybe another time Ubi.
