Equip your handgun and aim the on-screen reticule at any torch or suspended light. Often times the reticule will turn red and deliver a slight jolt in the Wiimote to indicate ammo or a treasure that you can shoot from the light and retrieve. This is a slight advantage not available in previous versions of the game.

When Ashley is wearing her alternate armor suit she is indestructible. If anyone tries to pick her up they will fall down. When knives, bows, or chainsaws hit her, she is unaffected. When you play as Ashley and a zombie grabs you by the neck, he drops you immediately. When the movable armor suits swing their swords down on her she never gets hurt. When Leon has to catch Ashley he catches her and nearly falls over then holds his back in pain. When Ashley crawls on his back he grunts in pain.

If you find yourself surrounded by some parasites of Los Ganados or Los Illuminados and do not want to waste ammo, quickly throw a flash grenade. Once it explodes it should make the parasites explode and die, saving your other ammunition.

After you use the chief's false eye to open the door, walk up the hill until the truck comes at you. Shoot it as usual and get back. Once it explodes walk back up the hill, but go backwards. Keep going all the way to the castle and you will avoid facing the enemies that would usually appear.

To earn easy money while playing through the game again, carry an empty Handcannon. It costs no money to have, but you will pick up ammunition for it occasionally. This is worth more than any other type of ammo in the game. After collecting the ammunition, sell it to the merchant. Try using the Chicago Typewriter as your main gun while doing this.

You can maneuver around U3 while you are in the giant crates. When you get to the gate it will follow you. Run around and shoot it, bringing it closer to explosive barrels. When you run out of barrels, fire either your shotgun or magnum.

If you find your rifle is empty, you can also defeat the Regenerator by shooting a mine into the spot around the parasite. If it is on its back, just shoot out its legs with your handgun then fire a mine into its back. If this does not work, scout out where the parasite is on the Regenerator and try again.

Tap A(2) when the "Open" command appears by a door to kick it open quickly. Doing this will also damage any enemies behind the door at the time you kick.

At the title screen press the - button and you will see a movie clip press it again 2 more times and in total you will see 3 movie clips. (In short press - button at title screen 3 times for 3 different movies)

Go to the inventory screen and select the Stricker. Exit from the inventory and press the B button and then quickly press the minus button. Equip any weapon besides the Stricker and leave the inventory screen. Now the glitch is activated and you can move twice as fast and shoot twice as fast but once you select the Stricker, the glitch will be deactivated.
