Guerrilla Games' Killzone The Tres is set to unleash a public beta on October 25, the PlayStation Blog promises. Of course, there's a catch: in order to get in on it, you'll need to be a PlayStation Plus subscriber before the beta rolls out, and download a custom Killzone 3 XMB theme, which'll release on October 19. The first 10,000 to download the theme will get access -- 5,000 from the US, 5,000 from Europe.
You'll also want to keep an eye on your email inbox, because Sony plans to mail out codes on October 25 to the lucky 10,000 who snagged the XMB theme first. To help tide you over, Sony's got a new trailer, which you can check out past the break.
