Robots!

From BoardGameGeek:

THE SIXTH WORLD WAR! The Third World War destroyed the armies; the Fourth World War destroyed the cities; the Fifth World War destroyed all life on Earth. The space colonies survived, however, and two hindered years later man returned to Earth. But not to stay -- only to plunder the riches of his former world. Robots were used to salvage the ancient technological sites. One day the Robots of two salvage corporations met at a particularly valuable site, and fired on each other with their mining lasers. The Sixth World War had begun: Robots! is a science-fiction game of fast action and sudden destruction. Players construct their own Robots by combining weapons (Gun, Missile, or Laser) with chassis modules (Track, Hover, or Droid). Newly constructed Robots move out from the factory salvage ships to capture resource areas, then mine the resources to produce new Robots, which then capture more salvage areas. Robots! is an exciting game for two or more players. - Multiple Scenarios and a Campaign Game - Complexity Level: Fairly Easy - Playing Time: One to two hours - Designers: Mike Joslyn and William F.
