Looking at the cover art for ultimate extinction, it may be something similar to the "kill god" storyline from the authority, but hopefully won't be complete and utter crap like that one was. The gigeresque art combined with some good storytelling could make for an interesting package. While it's true that the guy recycles a lot of his ideas, i think that's because some of them are really good ideas at their core and let's face it, with such global knowledge these days it's really hard for a work of art to not be derivative of something else.
