If you want to be one of the first to start the third round of battles against the Helghast in Killzone 3, it's gonna cost you. The main requirement to get into the October 25 Killzone 3 Public Beta Trial is to have an active PlayStation Plus subscription.

Still not convinced to put in all that effort? Have a new gameplay trailer to get you going on jumping through those hoops:
