Uncharted 2 demo now exploring PSN

Perhaps the biggest addition to the PlayStation Network Store this week won't cost PlayStation 3 gamers a thing. Those not yet convinced that Naughty Dog's highly acclaimed, multi-award nominated Uncharted 2: Among Thieves is worth their time can pick up a free single-player demo for the game beginning today. The multiplayer-centric PlayStation Heroes pack, which contains seven character skins from other high-profile PS3 exclusives, such as Killzone 2 and Resistance 2, is also available for $4.99.

The PS3 has a trio of original games added to its downloadable library this week as well. VooFoo Studios' Hustle Kings brings billiards to the PS3 for $9.99. Thexder Neo, from Square Enix, is a revamp of the classic PC side-scrolling shooter and features new graphics, features, and modes, as well as six-player online action, for $9.99. Having previously released the game for the Xbox 360 and PC, Wanako Studios will be bringing its top-down shooter Assault Heroes to the PSN this week for $9.99.

Two PSOne Classics also surface on Sony's store this week. Originally released for Sony's first gaming console in 1996, Epic Games' Extreme Pinball is available for $5.99. Bullfrog Productions' futuristic racer Hi-Octane: The Track Fights Back also zips in at the $6 price point.

There's a dearth of content on the PSP store this week, though four new PSP minis will see release. The new micro games released this week are Dracula - Undead Awakening ($4.99), Pinball Dreams ($6.99), Route 66 ($3.99), and Deflector ($3.99).

A full list of the week's deals and new PlayStation Store content, including themes, wallpapers, demos, and add-on content, is available on the official PlayStation Blog.
