Quad-legged Stationary turret with a Heavy Barrel there often found in Team-based games only and are barley seen in Black ops mode.
How can i tell if they seen me?[]
Sentry Turrets have one goal in this game and that's to stop Spawn killers from entering the base, The best option to avoid getting into a fight is to avoid getting locked on if you see a Red band with a "X" in the middle then that means your locked on and the Sentry will continue shooting at you until your Dead or Out of Sight.
Can Sentry Turrets be Destoryed[]
No, they can't be destoryed but they can Be affected by EMPs for a Couple of Seconds and no one knows for sure if they can be destoryed or not in Multiplayer.
