As a final push, I have uploaded a sample of the book, the mutants section. It has all the rules for using mutants in Nuclear Renaissance, plus some illustrations and a short story by Gareth "Gadge" Harvey.
I haven't quite met the goal of £1200 to get the rule book reprinted, but I have decided that I will go ahead anyway with this. This means I've added a whole load more of the rule book and expansion combo rewards to the campaign, and will extend this further if it sells out again.
