The Scar-H is my current favourite gun at the moment. There’s a slight upward recoil that you have to control by either burst firing or aiming at the body and with the recoil will land you more headshots. I’ve recently unlocked the foregrip which has helped.
Here’s a game of Team Deathmatch on Carrier playing with Hockey Glory where you’ll see a lot of the enemies start to quit/dashboard especially once I get my kill streaks going fairly early in the game.
Sorry for not including a commentary this time around but enjoy the video:
