PlayStation Plus subscribers will get 150MB of online storage space to back up their PS3 saves, meaning if you upgrade to another console (or go to a friend’s house), you can still have access to your Killzone 3 progress.
What’s even better is that it supports “copy-prohibited” save data, the ones where you can’t just dump onto a USB drive and transfer to another PS3. You can get PS Plus for $US50 a year or $US18 for three months.
