Because the game’s controls are for an Xbox, it’s difficult to remember certain things. Here is a quick guide in case you forgot how to do the Stealth Kill.
A lot of times during the game, there will be times when you need to get by(or eliminate) certain guards/enemies that walk around in a patrole.
Slowly, move in behind the guard until you see the icon pop up above his head.
Press the “F” key when the icon shows up, and let the REKToning begin!
