Doom had a beginning. After id Software completed Spear of Destiny
and was ready to start on their next-generation game, it was time to start
drawing up plans. Enter the Doom Bible. This design document,
written by Tom Hall in late 1992, was the original guideline for what would
eventually become the shoot-em-up we all know and love. Doom was
a different game back then: six episodes? Multiple characters?
Cutscenes? While much of the material within the 16-section Doom
Bible never found its was into the actual game, some items did; and their
origins are now fully explained. Ever wonder why it's called the
Soul Sphere? The Doom Bible had the answer. Did you know the
word "gib" was around in 1992? Yup, it's there. If you've ever
wondered what Doom's early stages were like, this is the document to read.
