One hit kills
When playing as either 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.
Extra inventory slot
When 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.

Collecting Leeches in Leech Hunter mini-game
While playing the Leech Hunter mini-game, kill everything in the Mansion, Train Tunnel, and Basement before picking up any of the leeches. Once you pick one up, you cannot put it down. Each player can find a maximum number of 50 leeches (100 total leaches in the game). One item slot can only hold 10 leeches only -- be careful.
