Not only will participants get an exclusive look at the explosive cinematic experience and a chance to hone their skills ahead of launch, but they'll be able to shape the final experience themselves - the trial will call for fans to provide honest game play feedback, report any bugs and cheats they find, and help test the network code in large-scale, real-world scenarios.
But you've got to be quick! Access will only be granted to the first 10,000 PlayStation Plus subscribers in PAL territories - to secure a place and ensure you don't miss out, follow the steps below:
1. Become a PlayStation Plus subscriber: access is limited to PlayStation Plus subscribers, so if you're not enjoying the many benefits of PlayStation Plus membership yet, now is the time to sign up!
2. Download the exclusive Killzone 3 XMB Theme from PlayStation Plus section of the PlayStation Store on October 14
3. Check your email! If you're among the first 10,000 to download the Killzone 3 XMB Theme, you will receive an email on October 25th containing the Public Beta Trial promotion code and further instructions through the address you registered as your PSN Sign-In ID
