After many moons of searching, I have finally found my own copy of Space Hulk. My roommates and I have played through several missions, and were looking to start incorporating all the models we have sitting in our closet (lots of marines, orks, IG, chaos, daemons, grey knights). I've seen several different variations, and know that they've had rules at one point... so i'm not sure which ones are balanced and which are not so much. do any of you vets have supplemental rules that you prefer?
