DOOM: 17 Easter Eggs, Secrets & References You Must Find

9. A Revenant Poster

Anyone who's played the multiplayer will be more than familiar with having their eyelids blown out by the ferocious Revenants; creatures with huge missiles on their backs who'll turn you to mulch in seconds.

To that end, it seems someone's been putting up flyers to warn of their presence, as user Untamed64 found out. The poster reads:

"This is a super scary thing. It is identified as something too spooky for me. Why for the love of god does this thing have missile launchers on it's shoulders as if it weren't enough this thing being the Damn Boogeyman. If you happen to encounter this abomination either run for life or kill it with fire or maybe some big gun."
