Sixteen years after the end of the world, the United States government survives as a small council of legislators and a combined armed forces company led by acting President and Secretary of the Interior Rachel Norman.

The Government in Isolation works hard rebuilding the country from the inside out, based in the Midwestern United States. Over the past few years they have brought the survivors from scattered isolated desperates to small agrarian communities. They have done good work, improving the lives of hundreds, but something stands tall, casting a dark shadow across the farmland:

Chicago.

All of the Government in Isolation's efforts to recover the windy city have failed. Only a few tentative expeditions into the city have been made, but rather than grateful survivors scavenger parties have found entrenched and aggressive gangs uninterested in the salvation President Norman has to offer.

Direct attempts at diplomacy and conquest have failed. It's time for different tactics.

It's time to send you in.

Second City is a post-apocalyptic sandbox game set in the ruins of Chicago. Players are an elite group of operatives sent in by the remnants of the US government to infiltrate the gang-held metropolis as a sleeper cell. Once inside, communication with their handlers will be limited, giving the PCs free reign to establish themselves as they see fit... get to know the local power structure, play politics, build up the city, or even start their own faction.

The game is run in GURPS using the After the End books, but players don't need access to these or familiarity with the system to play.

Got room for another character or two. The PCs have already reached the city, so joining at this point means you're not part of the original mission, but rather allies the PCs have made along the way.
