It's a nightmare. You are trapped in an abandoned mine with an injured comrade at your side against God-knows-what. Make your stand, get out alive. Three words of advice: shoot to kill. These things are not human, they are monsters..
Snipe the snipers before they snipe you. Once you start shooting, the sniper timer will count down fast so you may want to try and remember their positions if you can. Watch out for the sneaky soldiers that move in and out of cover.
