Better hunting gun use

If you have the hunting gun with unlimited ammunition from Leech Hunter mode, equip Rebecca with it. She shoots faster than Billy. Billy shoots once per second, while Rebecca can shoot about two or three times per second.

Better shotgun use

Once you get the shotgun, do not use it. Instead, leave it in the room with the scale you put the two figures on. Find, but do not pick up, lots of shotgun ammunition. After you save her from the pit, give all the hand gun ammunition to Billy and collect the shotgun ammunition. If you get it all, she will have about 60 rounds, which is much better than using two hand guns.

Custom handgun

When you are in the draining room in the facility basement, you will find the Duralumin case. You have to enter a code, which is "385". The case will open and you will find handgun parts. Combine these with Billy's handgun for a more efficient handgun.

Easier game

When you start the game as Rebecca, get to the point where you meet Billy. He will say that they need to cooperate. When Billy joins you on your mission, it is best if you have him in control at all times since he has stronger defense and will not get damaged as quickly as Rebecca. Note: This is the same in all modes.

Extra inventory slot

While playing as Billy with Rebecca as the alternate character, have Billy hold all the pistol ammunition for both characters and keep her gun fully loaded. This gives you one free inventory slot.

Killing zombies

While using the shotgun, aim down at the zombie's legs and shoot it. He will fall. Then, take out the handgun and shoot him one more time.

Leech Hunter Game

Clear Game on any Difficulty.

One-hit kills

While playing as Rebecca or Billy and you get bit by a zombie, move the character opposite of your main character directly behind the one you are controlling to have him or her shoot the zombie in the head and kill it in one hit, while the zombie deals you no damage. Note: You must have pistol equipped to save ammunition for a one bullet kill.

Safer and faster shotgun reload

To reload the shotgun quicker, go to the item screen. Combine the shotgun ammunition with the shotgun. You will be able to attack again without having Billy or Rebecca reload and waste precious time.
