Mission 1: First stage bonus
When you start the first stage, you will see an arrow sign at the left part of your screen. Jump above it and shoot downwards. It will give you a bonus chest.

Mission 1: Hidden items
When you get to the middle of the level, there should be three towers with rocket launchers on each one. Destroy these towers. After it is destroyed, stand where the middle tower used to be (there should be a door). Shoot upward to get bananas, apples, or a combination of both.

Mission 2: Extra points
At the bottom of a cave will be a skeleton. Slash it to get a ruby inside that gives about 10,000 points. Note: When you get the ruby, run. A stick of dynamite may appear.

Mission 2: Gold tokens
When you are going to battle the Boss, you must go up the spiral, which has a lot of treasure cases. In order to do that, jump on top of the arrows. Throw a bomb at or shoot the second arrow that points upward. If done correctly, you should get some golden tokens.

Mission 3: Big Shotgun
The Big Shotgun is the best gun in the game. It can be found on mission 3. Go to the first train car holding objects. It is covered by a white cover. There should be a prisoner directly in front of the cart. Untie him and rescue him. He will give you the Big Shotgun. Note: The background voice will only say, "Shotgun" and not Big Shotgun. The way you tell if the weapon is big or not is by looking at the letter. If the letter looks like it is coming out of the frame around it, it is a big weapon. For example, "s" is a small shotgun, "S" is a Big Shotgun, "r" is a small rocket launcher, "R" is a Big Rocket Launcher, etc. Some weapons do not have big versions. You can locate the ones that do and the ones that do not by looking at pages 9-10 in the instruction manual.

Mission 3: Bombs
After you leave the Camel, you will encounter a lot of enemies with swords and a big barrel of TNT. Kill all the enemies, then jump on top of the barrel edge (the one near the water). Throw a bomb into the upper layer where you cannot reach. A man will appear and give you bombs.

Mission 3: Keep cutting dead soldier with knife
When you are on the train, in the beginning of the stage you will see a soldier sitting in a chair. Go up to him and attack. You must be close enough to cut him with your knife. When he is dead you can cut him up more until an item appears, such as a fruit or a crystal.

Mission 4: Laser gun
Once you start mission 4, shoot the car that is behind you. You will get the laser gun after it explodes.

Mission 4: Jet Li in background
Advance through the mission and go to the part where you fight the double-decker bus. When you are there, look in the background. Jet Li will be on the billboard.

Mission 5: Super grenade
In the subway, destroy the third subway car that passes by. Use bombs and gunfire and a super grenade should be in it

Hint. Easy gun pickup
During mission 4, 5, or the final mission kill an alien in a pod to get a heavy machine gun, laser gun, rocket launcher, or enemy chaser. Note: This does not happen all the time.

Avoid vehicles getting hit
When you are in your vehicle and will be hit by a projectile, quickly press [Down] + [X] to escape, then jump back again to the vehicle. It will blink for a short time and will not get hit.

Final mission's Sub-Boss' weapon
At the final mission, you will eventually encounter a sub-Boss with a giant weapon. Kill him, and he will be eaten by a giant shark. You will see his weapon at the place where you killed him. Get it to have Heavy Machine Gun ammunition.
