This is a survival mod for Doom:The Board Game. I don't know if anyone has done the same thing but I post it here anyway. It features two marines and two invaders. Basically The Invaders are divided into two for ease of play. First Invader can only control Melee creatures, the second one controls only the ranged attackers. You can also download the pdf from here: http://www.boardgamegeek.com/file/info/32286

v1.1 changes:
Marines start with 20 health
Plasma Rifle description: I forgot to add the 1 round limitin the previous version

This document contains 4 pages. First three pages describe the rules and the fourth page provides tips on playing. Have Fun! The rules are nearly the same as the board game so don't worry about memorizing a lot of new stuff

I don't have the expansion so this mod only covers the base game. You can add the expansion stuff to the mod but I can not guarantee that it will work.

I will be very happy if you can provide some session reports about it.

Edit:There is a small typo on page three. The marines with survival ops ability start with 23-health not 22!
