Sony Computer Entertainment of America continues to expand its PlayStation Plus line-up for PlayStation 3, not only bringing players some love with Deus Ex: Human Revolution and Saints Row the Third, but also adding three more blockbusters.

First up is Uncharted 3: Drake's Deception, which will include both the single player campaign and the free-to-play multiplayer bundle, which will be free of charge to subscribers.  

The second title is 2K's wonderful strategy/tactics action game, XCOM: Enemy Unknown, where you pick from an elite squad of soldiers and battle aliens. Once someone’s dead, he or she never returns.

Finally, Sackboy hits the road with the kart racing game LittleBigPlanet Karting, a collaborative effort between Media Molecule and United Front Games, creators of ModNation Racers.  With a robust editing tool and hours’ worth of modes to experience both off-line and online, this is one sweet ride.

The games will be available this Tuesday as part of the Instant Game Collection.  No word on when they're slated to leave, so download them immediately.
