This was the first adventure I ran for my d20 Modern group. The PCs came from 'today' so the idea of a missile silo to explore was a great opening for them, familiar yet a good view into this new world they found themselves in. Everyone loved the adventure and took full advantage of the rooms based on the descriptions. The only downside was when the one new player, running a deaf mutant, decided to never listen to my descriptions and dove head first into rods sticking up in the shallow water (shallow where he dove in). ugh but a good laugh for the rest of us.
