Metal Slug 3 Hidden areas in Stage 1

Near the beginning of Stage 1, you will see a submarine floating in a pool of water. Hold Down to walk into this area, and jump 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, jump 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. Additionally, you cannot enter both hidden areas during the same turn.

Getting Thunder Cloud in Stage 2

In Stage 2, you can get the Thunder Cloud. Around the middle of the stage, you will see a lower area 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 reach you in this area. 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.

Hidden area in Stage 2

Around the end of the middle part of Stage 2, you will see a sign above a frozen-shut cave that reads “ICEMAN”. Walk to the left to go over to it, 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.

Curing 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.

Monkey helper

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.
