Assassin's Creed: Unity

Assassin's Creed: Unity Achievements


Perform 10 Co-op sync kills.  

To perform a sync kill, you and a partner must be killing an enemy at the same time (assassination). You will probably get a majority of these without trying while completing the various missions.

I need one other person to help me with this. I think I already got most of the co-op achievements for this game unlocked. I'll help somebody get a few of theirs if they help me unlock this one. Add me on xbox one my tag is Yellowalloy4

This popped for me even though I wasn't the one doing the kills. I think I actually made three on my own. This popped during a co-op mission for me after two other players did a co-op kill.

Connection issues with this game have plagued it fro the beginning. For the past month i have not been able to join up with people. It will either showits jumping into a mission than jump out back into the world, or start a mission solo. Sometimes it will just stop looking for people altogether when in waiting mode.
