To board the helicopter at the end of level 5 you must first allow the helicopter to leave the screen, then run to the end of the building and jump in the direction that the helicopter left, making sure that you completely exit from the screen.
During play, type "HI TO MSLG". Nothing seems to happen, but you will now have infinite lives.
You start off in a sort of open air theatre, so go through the curtain and punch the flashing yellow box to reveal a trap door on the open air theatre. Drop through the trap door and you will be under the theatre where you should find a key (in the bottom left corner - take it!).
You must now find the nunchack's. They are in two parts, both parts are in the two women's toilets!. Pick up the hamburger from the hamburger stand and use it to top up your energy. There are some shurikens in a box between two benches on the screen before the juggler.
To get past the juggler just keep somersaulting. Climb up the side of the walls on the screen after the juggler then go to the right.
Jump over the gaps and then collect the staff. Remember when climbing down the walls to walk backwards towards the wall! Collect the map after climbing down the wall (it's on the floor).
Go to screen with the gate on and open the gate with key you collected earlier. On the next screen you appear on their should be a river with a boat floating down it. Jump onto the boat then off the boat onto the other side of the river. On the next screen should be a swarm of killer bees. Avoid these and make your way to the top right hand corner.
Jump over the little bit of water, this will take you onto a island. Use your staff to push the boat - it will now start to make its way down the river. Go back to killer bees screen and take the other exit (top left). You will now be on the final screen of this level. Jump onto the boat that you set in motion, then again jump onto the other side of the river. Then go up the path you see to finish this level.
Make your way to the workman's hut and pick up the manhole key that is inside. Warning! when crossing the roads make sure the lights are in your favour. If their not you will get run over. When you enter the screen with the flashing door, kill the baddie and kick down the door.
Enter the martial arts shop, beat up the shopkeeper and collect the sword from the wall. Make your way To the drunk lying by the roadside and take the bottle from him. Take the hotdog from the hotdog stand to increase your energy. Exit this level by using the manhole key to open the manhole (obvious or what?!). Then drop down the hole and the level is finished.
Walk through the first three rooms, then take the right hand exit and collect the key. Go back into the last room and jump the gap.
On the next screen, slowly walk forward until you see a spider fall. Quickly follow it and exit the screen. On the next screen, use the key to open the grate and drop down. Whatever you do, dont go through the blue door. When you come to a set of three doors, take the middle one, then follow the path until you come to some more doors. This time take the farthest from you. On the next screen, don't go through any of the doors or you'll die. Instead, jump the rats and exit via the path.
Keep going until you find some more doors and go through the door nearest to you. On the next screen, kill the man then, holding the bottle (taken from drunk on level 2), walk into the torch on the wall until the top of the bottle turns red. Now kill the alligator by throwing the bottle at it and go through the door to finish the level.
Go through the maze of boxes on the right of the start screen and then empty your hands and go to the next screen. Climb up the ladder to the catwalk and left. Kill the bloke then collect the credit card.
Now make your way to the other far end of the catwalk, then go through the door. Pick up the food. Once you've collected the food you can go back to the ladder and back onto the floor. Now take the right hand exit and follow the path until you get to the rail cars. Wait for one to pass you and then somersault over the lines. Keep going along this path and you should come to some more rail lines.
Once again jump over the lines. Follow the path round until you reach a room filled with bottles. Take the bottom left exit, kill the man on the next screen, then on the following screen you should find a flashing white object in a box. Hold the food and collect the box - this poisons it!. Go back to the bottle room, take the exit on the right and you should be face to face with a hungry panther. Hold the food chicken and walk forward slowly until it sits up. Take one more step forward and use the pick up method to lure the panther towards you. It will then take the chicken, eat it then die. Go past the dead panther to the next screen and use the credit card on the box near the lift to enter it and go up in it.
Leave the first screen and go through the blue door and touch the computer in the office. The computer will give you a number. Write this number down if you cant remember it. Go back out and follow the path down and around to a screen with two pictures on it.
Go through the top one and walk over to the desk near the desk near the pictures. Stand at the bottom and use the pick up movement to touch the button on the table, thus opening a secret door. Climb the ladder on the next screen to reach the second floor of the offices, then go out through the door. Go through to a room with a fan in it, stand close to the wall and face backwards. Keep nudging the ninja backwards until you reach the back wall then go to the grate and use pick up again to open it.
Go out onto the ledge. Follow the ledge around and go up the ladder. Kill the next man you see then put away all your weapons. When you get to the last screen of this level you will see KUNITOKI making his escape in a helicopter. Stand at the top right hand corner of the screen and when the helicopter leaves, somersault off the building and onto it's landing skid. The helicopter will now carry you to the next level.
This level starts with you still hanging onto the helicopter, so to get off without killing yourself, pull down on the joystick when it flys past the turret and you should drop down safely. Somersault forward, landing in line with the turret on the left, then somersault again to land on it. Now gently nudge left off the turret and walk along the strip until you reach the window. Face the window and somersault again to land inside the mansion. Walk down the corridor into the next room,go through the big door and collect the rope so that you can go down the dumb waiter.
Turn off the alarm then walk behind the plant where you should find an entrance. Punch the switches on the wall to switch on the lights in the maze which is on the next screen. Get yourself through the maze and you should find a steam engine. Redirect the steam by touching the right hand switch on the boiler and you can walk through the door to the last part of the game.
Kill the gaurd in the first screen, then walk through to the room with the star shape on the floor. Go over to the tapestry on the wall and lift it up to reveal a safe. Unlock the safe with the combination from the computer in the office and take out the orb. Kunitoki will now enter the room and youve got to kill him so that he falls somewhere inside the star on the floor. Before he comes back to life, light the candles on the points of the star and put the orb back in the safe to finish the game.
