Just a quick update of some info found out about Killzone 2. According to our friends over at everdayplaystation the title will have custom soundtrack capabilities via multiplayer, though single player will not have this feature.
Here is a direct quote from Seb Downie, the QA Manager of Killzone 2:
Only for multiplayer via the XMB. In Single player the music is designed to match the action so it would be hard for us to mix up your favourite boyband.
