When the human race finally leaves the Earth to live as gaseous nano-clouds amid the stars, our supermarket trolleys will reveal their hidden sentience and rebuild themselves as a race of gladiatorial destructo-borgs. This, you understand, is not the back story to Metal Drift. It should be. I certainly experience metal drift with most of the trolleys I end up wrestling round Asda as we collect ready-to-decay food for our weekly engorgement. One day, when I am in charge of the back story of all futuristic combat games, things will be okay. In the meantime you’ll have to make do with the meagre efforts of the developers, who explain their Metal Drift thus: “a vehicular sport combat game set in a distant future.” That doesn’t explain my motivation, but okay, we do expect vehicular war in the future. In fact, we can expect it right now, because the demo is on Steam.
