PS Store adds demo, update

PlayStation 3 owners can now head over to the PlayStation Store and check out some new stock, as Sony has added three items to the online marketplace.

Now that the PS3 has launched in Europe, Sony is giving gamers across the globe the chance to prove they are the best at Gran Turismo HD Concept. A new update for the free demo adds global leaderboards, showing the top 10 worldwide rankings for each car and mode. The update also adds full force-feedback support for Logitech's Driving Force series of steering wheels.

Also available for download is a demo for Armored Core 4, From Software's mech-combat game. The sample features three single-player missions from the full game. Completing the trio of new items is a free HD trailer for Grand Theft Auto IV.
