Sony has just announced that it will be adding a number of new titles to PlayStation Plus, free to download for customers. Sony's add-on subscription service will see the new games added to its arsenal starting tomorrow, with Infamous 2, Saints Row 2, and Little Big Planet 2 amongst those offered for PlayStation 3 owners. Over 60 games have been made available as part of PlayStation Plus thus far, and with the new additions, Sony Computer Entertainment of America CEO and President Jack Tretton touted the service as "an instant game collection" — for $5 a month, of course.
