If you put a scratch on your disc right under the rating area(where on the disk, hit memory is stored) it will make every hit you make a one-hit kill, online or offline. You will have to restart the game after scratching it. This happens by erasing some critical data for combat hits and as effect, your hits power is randomly set at 9999999999999999. This glitch was discovered on the GameStop forums by a game tester of this game who was experimenting. PLEASE BURN A DISK FIRST, due to recent confusion and problems this may not work due to human error. As long as you get it in the right spot it SHOULD work, happy gaming!
