Codes, Cheats & Spoilers
 =>Save Bernard's Life: If Bernard should somehow get killed, have some one
give Weird Ed his package. When Ed tells you about the microfilm, switch to
Bernard. You will not see Bernard, but move the cursor to the roll of
microfilm and GET it. Ta-dah! Bernard's invisible ghost can now be moved
throughout the game... but the "Dead Kid" count will not change... if 2 more
deaths occur, the game ends. You can try this trick with the other kids,
but I can only get it to work with Bernard.
=>Escape From the Dungeon: Have one kid use the loose brick in the dungeon
and the door will open; another kid can dash out of it.
=>Nuke The Hamster: Quite simple... only Razor or Syd can nuke the hamster,
and this can only be done in the original supply of cartridges. Some later
versions have this function removed.
=>VirtualNuker: It is possible to snag things from the microwave while it
is still shut. To make this useful, nuke the hamster but remove it during
the microwaving process. When the microwave finishes its cycle, you will
find some exploded hamster bits inside, even though you already removed the
hamster.
=>Explosive Keypad: Go through the steel security door to the hallway with
striped wallpaper. Go to the 5th strip to the left of the door and look for
the keypad. "Use Keypad". A digit console will appear. Punch in some numbers
and you will hear some sounds and an alarm. Soon the mansion will blow up.
* This was the copy protection in the PC version of the game; the
programmers kept the device but removed the need for copy protection.
=>Fool Edna: Walk a kid into Nurse Enda's room and immediately switch to
another kid. Wait 20-30 seconds, then switch back. You should be able to
freely move the first kid through Edna's room even though she's inside.
=>Multiple Endings: To see all the endings, you'll need to a)send off the
Meteor via Edsel, b)same as A but kill Dave, c)let Meteor Police nab the
Meteor, d)give Meteor book deal, e)same as D but kill Wendy, f)same as D but
call Meteor Police first, g)first fire off the Edsel, then go to the dungeon
and grab the Meteor, carry him through the destroyed garage, through the
house, and feed him to the plant, h)kill all 3 kids, i)blow up house.
