Castle Crashers make belated arrival on PSN

This week's PlayStation Store update features a bevy of long-awaited releases, but none longer awaited than Castle Crashers for the PlayStation 3. Originally released just over two years ago for Microsoft's original Summer of Arcade Xbox 360 promotion, The Behemoth's four-player arcade-style beat-'em-up has finally made its way to Sony's system and is selling for $15.

Also debuting on the PS3 this week is Telltale Games' Sam & Max Episode 5: The City That Dares Not Sleep, the final chapter in the current season of the episodic adventure game. It is available only to those who purchase the full season (called The Devil's Playhouse), but Telltale and Sony are offering a discount for the bundle, making it available for $20 instead of its normal $30 price tag.

The PSP has its own new addition to the downloadable game catalog in the form of Sega's Valkyria Chronicles II. A handheld-only follow-up to the 2008 PS3-exclusive original, Valkyria Chronicles II is set two years later and thrusts players into a Gallian civil war. The portable tactical role-playing game sells for $40 and casts players as a member of the Gallian Revolution Army, fighting a fierce battle against a tyrannical faction. Sony promoted a second PSP game, Ace Combat: Joint Assault, as being part of its update, but the game was not available as of press time.

Beyond the trio of new game offerings, the week's PlayStation Store update also includes a new addition to the PSOne Classics library, as well as high-profile add-ons and game demos. Bullfrog's Theme Hospital is the retro offering of the week, with Sony asking $6 to download the strategy sim to play on either the PSP or PS3. Meanwhile, BioShock 2 gets a single-player story-driven add-on in Minerva's Den ($10), and demos arrive for both Shinji Mikami's PlatinumGames shooter Vanquish and Ubisoft's deception-driven strategy game R.U.S.E.

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