Yes, the name was intentionally vulgar. Tom Hall originally named it 'BFG,' which was expanded in the manual as 'Big F***ing Gun.' It has since been sanitized in some versions.

Romero scanned his own face with a flatbed scanner to create the player's pain and death animations. He also posed for many of the weapon sprites, such as holding a chainsaw.

The PlayStation port actually had enhanced lighting and colored lighting effects, but it ran at a lower resolution and had fewer enemies on screen compared to the PC original.

DOOM was primarily written in C, with some assembly for critical routines. John Carmack used C for most of the engine; assembly was only for optimization in a few areas.

This is a persistent myth. DOOM was never used by NASA for training. The rumor likely started from a joke or confusion with other games like 'Marathon' or Quake.

DOOM was indexed (banned from public sale) in Germany in 1994 due to violence, not Nazi symbols—DOOM has no Nazi imagery. The ban was lifted in 2011 after a re-rating.
