User blog:DeadMenTellNoTales/Assassins Creed Unity New Features.

Ok from the top of my head:
 * Deeper custimization
 * Skill tree
 * RPG elements
 * 1:1 scale (holy shit)
 * Dedicated stealth button (finally...AC1 di not cut it for me..)
 * COOP
 * parkour up and down button(no idea how this works.)
 * No more counter kills(Kill streaks gone?)

This Blog could be just discussing new things in ACU, I dont mind speculation.
