Hint: Faster Shots
To lay down zombies faster, lock on to them by holding the R trigger, then rapidly tap the A button swiftly instead of holding it down for semi-auto fire. Your character should fire more quickly

Hint: Green Chemical
When you get the green chemical from either the container in the infirmary or underneath the church, you can use it to heal your poison status

Hint: Rebecca's Dodge
Press and hold the R trigger then quickly release and press again. If done correctly, Rebecca should step/dodge backwards quickly to avoid damage. Works best on zombies in close quarters

Get New Costumes
Simply complete the game on Normal or Hard Mode, and you will find the Closet Key in Rebecca's inventory when you begin a new game. Take this to the room where you got the Hunting Gun and use it to get into a costume room.
What can you wear? Billy gets a suit and Rebecca gets either leather or cowgirl apparel. Gzrau.
