Beamstrike

A free science fiction miniatures skirmish game. From the rules introduction: "Beamstrike - The miniatures game - is a set of fast paced, simple, science fiction war-game rules for tabletop battles using 15mm model miniature figures. A wide range of armoured vehicles can be fielded, from Tanks, to Walkers and Mecha. Rules for alien races, including generic ‘bugs’ and ‘greys’, add interest, and full rules allowing robots and androids complete the sci-fi repertoire."
