This is what I have done. I lost all my Space Hulk 2nd Edition in a flood early 2011. I wanted Space Hulk 3rd Edition, but $400??!?!! No way!!!! I did some investigating and research and found that I could make my own home-brew version and end up with a *better* Space Hulk game!
First big hurdle: Obtaining rulebook and mission book.
Stuff has started arriving this week and I imagine it will take me a few months to get it all painted, I'm making 2 squads (Dark Angels & Imperial Fists) complete with Librarians & Captains (the only models I've had to buy at *full* price)!
I plan to document the journey and list all stuff I obtained. I'll update with a link once I've got around to getting it up. (I'm also *refreshing* an old HeroQuest game I have as well.)
I cannot wait to play!
