If you are a PlayStation Plus subscriber, SCEE has opened up the LittleBigPlanet Karting beta for a limited time only. Starting now, you can download the LittleBigPlanet Karting Beta client from the PlayStation Store, but its only available for 24 hours.
Download the client before Friday 3:00pm GMT. The goal of the beta is to get feedback on the overall experience from Sackfolk who understand it like few others. Happy karting!
