Sometimes when you destroy the wooden crates a snake will jump out and bite you. If you keep slashing with your knife when the box breaks you can kill the snake and receive a healing egg.
Hint: More Money for Beerstein and Elegant Mask
When you find these items do not sell them right away. You can increase the value of the items with gems.
Hint: Reload Your Upgraded Gun
Whenever you upgrade your gun's capacity it fills the weapon with ammo. So don't reload before you buy the upgrade. This works great with weapons that have very little ammo (such as the magnum revolver 'Broken Butterfly'); after you use up the gun's magazine, simply look for the merchant and upgrade the ammo capacity.
Hint: Quick Aiming
There is a quick way to center your gun when aiming up or down. Simply tap the L1 button (takes out your knife) and you will quickly aim straight ahead.
Hint: Raise Max Health
If you mix: GREEN HERB + RED HERB + YELLOW HERB. It restores your health completely and raises your max health.
Hint: The First Shotgun
There are three main buildings in the village where you first see the chainsaw not-zombie. The shotgun is in the northeast building, on the second floor of the house.
Hint: Los Gigante
In Chapter 1-1, along the path towards the village you will run along a white dog trapped in a bear trap. If you help this dog he comes in handy later when you are fighting Los Gigante for the first time. About midway through the fight, you will hear the dog bark and he will come to your aid. Los Gigante becomes distracted, and begins to attack the dog rather than you.
Hint: Funny Character Animations
When Ashley is standing on a ledge and you are below her, look up at her and she will hold down her skirt and say something about you being a pervert and one or two other funny lines.
Hint: Double Broken Butterfly Ammo
If you buy the broken butterfly before you find it, you can hold twice the ammo. The shopkeeper will not sell you this gun if you already have it.

If you are low on health spray and herbs when at the lake take aim at the fish and fire away. When you hit a fish it floats. Jump in the boat and ride over the fish and take it. Depending on the size of the fish it will give you health.
Hint: Lake Shooting
When you are at the lake before you face Del Lago (the thing in the water) stand on the dock right before the water and start firing into the water. The creature will not appreciate this.

Hint: Big Money
