Let billy or rebecca get grabbed by the zombie then go behind the zombie and shoot him in the back of the head and he should be dead if not then as he is getting up shoot him again but usually he is dead after the first shot. Shoot zombies in the head to conserve ammo not in the mid section of them it takes about 4-6 shots with the handgun if you shoot him in the mid section repeatedly and it only takes 1-3 shots if you shoot him in the head and you can also knock down zombies in a row like dominoes hope this hint helps.

A very easy way to beat mimicry marcus (the leech man ) is to throw a molotov
Cocktail at him or shoot him with flame rounds then take billy's (or rebecca's)
Hunting gun or Shotgun and blast him 2 times usually he explodes on the 2nd or
1st try then on to the lying zombies. Any zombie that is laying there is usually
Still alive so just shoot the laying zombies when you come across one and if
Blood spurts up keep shooting him.

When you face the first marcus you can save ammo if you walk back down the steps you walked up I saved over 40 bullets doing this.

When you enter the underground maze go to the controll room and open the locker to the right of the controll pannel. collect the metal case and examine it to find the code on the back near the hindges. equiped the slides you get from the metal case.
