A few years ago I found an beat up old board game, in a consignment shop. I played it a few times and it was pretty fun. Just this weekend I thought I would find out more about the game. According to Wikipedia Milton Bradly Produced the game in conjunction with Games-Workshop. I think they mainly produced the minis.
Overall the game has received very good reviews and I remember it was quite fun to play. The game plays as a dungeon delve focused on bashing monsters heads in, and is a basically easy mode D&D. The entire base game can be found in a digital format here. Any way I thought it would be something cool to bring to the next 40k day to show off, some of the models are absolutely spectacular. I am unfortunately missing the core rules and one of the character sheets, though I think everything else is intact. I thought I would just purchase the missing pieces online, but I was surprised to see copies of the game selling for $100.
