Running Arcology Shutdown, my players decided to go to war with Deus, the AI. They decided that melting down the fusion reactors in the basement would certainly destroy that pesky AI. Yeah, Seattle wouldn't fare well, but that's collateral damage for ya. They pulled it off, but the AI simultaneously hacked into NORAD and made it look like an ICBM was heading for Seattle. When most of downtown disappeared in a mushroom cloud, the president began a full nuclear exchange.
We are going to continue playing among the ashes. The sun will be blocked out, which will of course kill all plant life.
Any ideas for cool, post-apocalyptic Shadowrun plots? Thanks!
