As ever, Sony's weekly update to the PlayStation Store's digital catalogue arrived yesterday with a metric shedload of new releases, demos, downloadable content, and other gubbins.

This week's new PlayStation 3 releases are the new Contra game Hard Corps: Uprising, which hit Xbox 360 last month, and Slam Bolt Scrappers, which somewhat resembles action-Tetris. PSone survival horror RPG Parasite Eve also arrives as a PSone Classic title for $6. The PSP gets Dissidia 012[duodecim] Final Fantasy's $3 prologue episode.

On the demo front, Crysis 2, PlayStation Move Heroes, Plants vs. Zombies, Slam Bolt Scrappers and Mortal Kombat are available to all and sundry.

DLC-wise, Marvel vs. Capcom 3 gets new characters Shuma Gorath and Jill Valentine for $5 each, or free to Limited Edition owners. Newly-released RPG Ar Tonelico Qoga: Knell of Ar Ciel gets a handful of new scenarios. There's also more Rock Band 3 and DJ Hero 2 tracks.

PlayStation Plus subscribers pick up a Full Game Trial for 2008's Prince of Persia, which got a downloadable release this week, as well as an assortment of unexciting themes and discounts.
