The Doom Alphabet Game

This game is very simple:

• Every post will contain a word or term that begins with the next letter in the alphabet prior to the post above it.
  
• All words/terms must be related to the Doom series, its ports or the movie in some way (no Heretic/Hexen please).
  
• You cannot re-use any words/terms, including plurals.
  
• Only one word/term at a time and no back-to-back posts.
  
• When we hit Z, start it up again.
