Per Kevin McCann (President and Creative Director, Tiki Games, Inc.) via PlayStation Blog:
Hey folks - I’ll keep this one short - the NOVASTRIKE update is finally out. Again, highlights of the update include trophies, tamed difficulty modes, customizable controls, XMB playlist support, and more.
You can also read about the NOVASTRIKE trophy requirements on PS3 Fanboy’s trophy page.
I’d definitely like to thank QA, developer support, and my account manager - they were very responsive in helping us get the update out this week. More PlayStation 3 News...
