2: DEFINITIONS
--------------------------------------------------------------------------
2.1: What is Blue?
Blue (blu) - a color between green and violet. A rather beautiful color.
2.2: What is Red?
Red (rehd) - a color between orange and violet. Some people consider it a
symbol of love. You will consider it a symbol of a) red keys, b) red doors,
or c) something's been hurt.
2.3: What is Yellow?
Yellow (yel-lo) - a color between orange and green. Now, I would duplicate
the DOOM ][ keys FAQ's attack on the color, but being in love with a blonde,
it would not be such a good idea. Of course she'll probably never play DOOM,
let alone read this FAQ, but still...
2.4: What is a Key Card?
A Key Card is a small object, found in DOOM, that looks like a computer
add-on card. They come in three colors, red, blue, and yellow.
2.5: What is a Skull Key?
A Skull Key is a small object, found in DOOM, that looks like a small skull.
As with the Key Cards, they come in red, blue, and yellow. Skull Keys
function identically to Key Cards.

at.
3.2: What do I need a red key for?
You need it to unlock red security doors.
3.3: What do I need a yellow key for?
You need it to unlock yellow security doors, and to remind you of your
beautiful blonde girlfriend while you're spending half of each day playing
DOOM :-)
