Blast Factor - hands-on

Among the games on display during Sony's PS3 preview event in San Francisco was Blast Factor, one of the first titles to be available exclusively through the PS3's online service. Pitting the player against malignant microbes at the cellular level, the game plays exactly how it looks: like a cell-themed version of Geometry Wars or Mutant Storm. As a little robot-looking thing, you'll bounce around in a two-dimensional, six-sided Petri dish, blasting in any direction you point the Sixaxis pad's right thumbstick at. Occasionally you'll get power-ups for your cannon, but the goal remains the same: fight off waves of what look like blood cells and cancerous polyps, clear the dish and move on to the next one.
