Doom

Note: This code requires a six button controller. PressB + C + Y + Z during game play.

The descriptions of the various enemies in the game are as follows.

• Former Soldiers: They resemble your old friends, but now they just fire pistols at you. They drop clips for the chaingun and pistol when killed.
• Former Sergeants: Meaner and tougher. They carry shotguns and do more damage then soldiers. They drop shotguns when killed.
• Imp: This creature throws fireballs and takes more bullets to kill.
• Demon: Appear in most areas and can rip your head off if you are not careful. If you see more of them, use the chaingun.
• Cacodemon: These creatures are ugly and have one big mouth. If they see you, they will fire lightning balls from their mouth. Use your rockets.
• Mancubus: You have to use more then a chaingun to kill them. Use ammo with caution.
• Arachnotron: Fires plasma energy at you. Use your rifle.
• Spider Demon: The ultimate enemy. Has a super chaingun mounted on her body. Use your plasma rifle or rocket launcher.

Enemies of different types do not have much respectfor each other. If they accidentally shoot each other, they willturn on each other. If you have very little ammunition or health,this can be used to your advantage. Enemies of the same type (withthe exception of any Former Human and Lost Souls) will not attackeach other.

Go to the dark section inside the red door area. Punch the wall behind the green armor at the back of the dark area. This will lead into a secret section.

Cheat codes cannot be used in nightmare mode. It isjust like the regular game, except the monsters are stronger andharder to kill. Enemies will keep appearing non-stop on each level-- you have to try and get to the end before more appear.

While running keep touching a wall to move faster.

• Listen for weird sounds, like somebody breathing very hard during the game. Those sounds are the brown monsters that throw fireballs. When the sounds stop, that means you have killed them all. However, there still may be normal enemies with guns and shotguns or pig monsters.
  

• The snorting sounds in the game are coming from the pigs. Once the sounds stop, that means you have killed all the pigs.
