Legion Assassin

The ''Legion Assassin" is an enemy you will encounter if the player sold    Legion to Cerberus in Mass Effect 2. It has low shields and health and is equipted with the Raptor Sniper Rifle. He is only seen on Priority: Cerberus Headquarters when you have to reach the most secure area. He will come down from the ladder and attack you.

Offensive- The Legion Assassin is armed with the Raptor so on high difficulties it is suggested to keep a distance. The M-37 Falcon may be of use. Garrus Vakarian is also good due to his overload ability

Defensive- The Legion Assassin has shields but not much else to defend himself. You will only encounter him on this one mission.
