As ever, Tuesday night brought a new round of games, downloadable content, trailers, themes and other gubbins to the PlayStation Network in Sony's weekly PlayStation Store update.

This week's new games are Might & Magic: Clash of Heroes, a revamp of the Nintendo DS strategy RPG, and action-RPG Dungeon Hunter: Alliance. While Dungeon Hunter looks about as original as every other title from Gameloft--i.e. not even vaguely--it's hard not to be curious about co-op dungeon crawling. Assassin's Creed also gets a digital release at $19.99.

On the demo front, there are trials for Clash of Heroes and Hothead's cannon fodder platformer Swarm, which was released in March.

Downloadable content releases include a Killzone 3 map pack, Bulletstorm's Gun Sonata, WWE All Stars wrestlers including a free Honky Tonk Man, Red Dead Redemption's pre-order bonuses, new scenes for Yoostar 2, and heaps more.

PlayStation Plus users get a full game trial of Assassin's Creed, the Killzone 3 map pack for free, and discounts on Dungeon Hunter and Clash of Heroes.

You can find the full update listing over on the PlayStation Blog.
