Dude it was beast by end of game. Damage increase mod, Silencer, like 3 ammo capacity increases, couple reload increases, and bought all the ammo I could find everytime lol.
Who needed the stun gun when a silent round to the skull would permanently put people to sleep unable to be woken up
Example; I had this cool little segment on one of the later missions. I knocked this guy out in hand to hand, but I alarmed another guy a little distance away. He comes running over, so I crouch behind a planter box. Right as he gets near me I hit cloak and walk behind him. He is looking all over for me as I put a round in back his head to put him nighty nighty.
So many cool moments in this game!
