You get to taste the "jetpack and exoskeleton vehicles." You need a unique PS Plus XMB theme off the PlayStation Store to 'opt-in' from October 14th.
Unless you're a PlayStation Plus member you may as well go sulk in the corner because you've got no chance this October 25th to get in the Killzone 3 multiplayer beta. Even if you are a PS Plus subscriber then only 10,000 are going to be selected.
"Those of you who make it into the Public Beta Trial are expected to provide honest gameplay feedback, report bugs and glitches, and help test our network code in real-world scenarios. In short, we’re counting on you to help us improve Killzone 3!" say devs.
To put your PSN name forward for the online beta you need to get hold of a special XMB theme that goes up on the PS Plus section of the PlayStation Store from October 14th onwards. Killzone 3 releases exclusively for PS3 in February 2011.
