Yesterday I finished my 79'th artifact and submitted it to my editor (Super Greg). As he has a creation he wanted to add, that makes 80 devices, robots, buildings, weird stuff and even weirder stuff to empower, confound, kill or drive insane player characters (and hopefully not their players). I really hope that you have had fun with the artifacts that have been released so far and I promise I did not hold back with those you have yet to read. And Greg's additions (the specific artifact and some additions to others) are no less than excellent. I am very lucky to have an editor like him.
Can't wait to see this book on Amazon along with my current works for Mutant Future.
