Counter-strike: Global offensive represent a new bid from Valve to capture the eSports scene on consoles as well as PCs. That would be good for everyoneinvolved, so Sony is helping to pimp it a little by offering an exclusive, 60-minute demo to PlayStation Plus members. The demo will arrive by auto-download on August 20, and is not otherwise available on the PlayStation Store. A community rep warns you’ll need to have automatic downloads enabled to nab the demo, so get on that. The full game releases on August 21 for $15, on Mac, PC, PlayStation 3 and Xbox 360.
