During Part IV: Grim Discoveries, after you have taken the elevator down into the cavern, you will face the Wendigo and three soldiers. Instead of feeding the soldiers to the Wendigo, knock the gun out of each of their hands and lure them to an open area. Next, position yourself so you can perform a level 3 strike on each of them simultaneously. You will be rewarded with 150,000 points and a dog tag if the "Claw Slam" Strike is successful. Finally, if you run away from the elevator, three more soldiers will rappel into the shaft with you. You can repeat the process as many times as needed for lots of points and dog tags. Note: If you die you will have to restart the level. For best results, use the "Invincibility" cheat.
