I probably haven't promoted it enough, but RPGObjects has run GenCon events for the last four years and this year won't be any different.
Revenge of the Terminals is this year's adventure for d20 modern and Darwin's World. As with all convention adventures, I utilize pre-generated characters. I've put them up for download so participants can pick their character (or if others interested in the adventure want to take a peak).
