Avoid Super Computer
With this trick you don't need to destroy the Super Computer! When you enter the computer's room, Solid Snake appears in the door frame. As soon as he appears, hold the control pad or joystick to the right and you'll appear in Outer Heaven's room! Now you can attack this Boss without having to fool around with Solid Snake!
Cigarettes, Tine, and No Traps
In Metal Gear you can actually use the cigarettes as a helpful item but not before you beat the Super Computer. After you have beaten the computer, a timing device is set for the building to destroy.
Once this has happened, run in the right direction and go through the door. You will meet the Boss of the enemy. When you have successfully destroyed this opponent, check your time to make sure you can escape. If the end Boss took too much time to eliminate you may find yourself in a critical position with very little time remaining. If you are dangerously low on time, then select the cigarettes and use them. This will reset the timing device to 2000 and give you the extra time you need to leave. While in the last room you can contact Diane on the transceiver for instructions on how to use cigarettes. To remove the pitfalls, press 'Select' when the trap starts to open up. The pitfall will stop. To remove it just hit the button for the weapon select mode and press select again.
