Leatherface or Chaingunner...these are my two ideal choices for a costume this year for my buddy's annual Halloween party.  

If I do leatherface, it will probably be some kind of hybrid between Hansen's and Bryniarksi's Leatherface.  If I do this, it will be scary and pretty identifiable.

If I do the chaingunner, it would be cool but not identifiable outside of people familiar with Doom II.  

Decisions, decisions...
