Stopped Dead Achievement in Assassin's Creed: Revelations
Obtain 3 Hidden Gun kills during a session of Steal The Artifact as The Corsair (Multiplayer).
How to unlock Stopped Dead
Ability: Hidden Gun
Ability Unlocked: Level 17
Character: The Corsair
Mode: Free for All - Steal the Artifact
You must first assign this ability to an ability set in the multiplayer menu. After picking Free for All and Steal the Artifact, make sure to choose The Corsair for the achievement. If someone else picked the character or you got put into another random match, you may quit out and try again. You will have a short amount of time to complete 3 kills. Each time you shoot the gun there is a 90 second cooldown before you can use it again. This means if you miss you will be wasting valuable time. Do not pick the artifact up and always stay on the offensive.
