Continue game play:
After losing all lives, press Start on controller two to continue the game using that 
player. 

Hint: Stage 1: Hidden areas:
Near the beginning of the first stage, you will see a submarine floating in a pool of 
water. Hold Down to walk into this area and hop into the sub to go to an 
underwater part of the stage. The next hidden area is at the part where the boat is 
located. Instead of getting on it, hop onto the ledge above it to find a secret hatch. 
Go inside to enter a cave-like part of the stage. Note: Every time you complete a 
secret area, you will go directly to the Crab Boss --- you cannot go in both hidden 
areas during the same turn.

Hint: Stage 2: Get Thunder Cloud:
In the stage with the zombies, you can get the very helpful Thunder Cloud. Around 
the middle of the level, you will see a spot on a low area of ground where two 
prisoners are next to a man in a business suit. Hold Down/Forward to crawl down 
to this area and save them. Note: Enemies cannot get you down here. When you 
rescue the man in the suit, he will pull out a cell phone and call over two 
bodyguards with suitcases which contain a gold coin and the Thunder Cloud. To 
use it, just shoot your gun when the cloud hovers over an enemy.

Hint: Stage 2: Hidden area:
The level containing the zombies has a secret and unique area. About the end of 
the middle part of the level, you will see a sign above a frozen-shut cave 
reading "ICEMAN". Walk to the left to go over here and shoot the ice wall blocking 
the entrance. Inside are numerous "ice men" and at the end of the cave is a 
buried Elephant Slug, frozen in the ground which you can free and ride.

Hint: Cure zombie or mummy status:
To turn back from a zombie to a human, use the Med-Kit item found in enemies or 
boxes. To turn back from a mummy to a human, find the bottle of Holy Water 
found in enemies or boxes. 

Hint: Helper monkey:
Throughout the game you will find a wooden crate containing a monkey wielding a 
gun who will help you fight enemies. Note: Do not rely on the monkey helping all 
the time. Sometimes he will stop to pick his nose and do other things.
