FutureShock!

From BoardGameGeek:

FUTURESHOCK has arrived, and with it, come brutality, mayhem and carnage, all on a single page that can be printed out, cut and turned into a tiny six-page booklet. FS is a set of incredibly simple skirmish rules for miniatures in your collection, focused on the post-apocalypse, but don't let that stop you from using it to fit whatever setting you prefer. In FS, players create warbands of thrashers and send them into small-scale engagements, rife with blood, mayhem and slaughter. Skirmishes are played on 1 by 1 foot battlefields with combat beginning on the very first turn. This inaugural issue of FS contains the complete core rules in a simple tiny booklet, with future installments to focus on: solitaire rules, scenarios, new weapons and items, mutations and much more. Welcome to the wasteland, Thrasher. Welcome, to FUTURESHOCK! -description from the publisher
