You may recall an article we wrote earlier this month announcing that ModNations Racers will be available on the PSP, alongside the PS3 versions. If you sign up to the ModNation Racers website before March 2nd 2010 you can score yourself some exclusive XMB themes for your PSP next month.
If you have already registered, you will automatically get the themes next month too. In the mean time, check out the video below to learn a bit about how both games for started.
