Accio demo! Lego: Harry Potter trial hits XBL

The only new demo this week is a trial of the aforesaid juvenile wizarding release. Lego: Harry Potter Years 1-4 arrives on retail shelves June 29 for Xbox 360, PlayStation 3, and Wii, but the trial for the Xbox 360 edition of the block adventure game is now available in all regions except Japan.

Coming to the Xbox Live Arcade June 9 is Earthworm Jim HD for 800 MS points ($10). A remake of 1994's Earthworm Jim, the HD cousin features up to four player co-op, 15 levels, and a remastered soundtrack. In addition to the original levels, developer Gameloft has added three exclusive-to-the-remake levels and achievements to collect.

Microsoft's digital marketplace this week added two Games on Demand titles. Volition's red planet action game, Red Faction: Guerrilla, is now available for 1,600 MS points ($19.99) everywhere except Japan. The open-world action game has players suit up alongside the rest of the Red Faction, fighting against the good-turned-evil Earth Defense Force. Nearly everything in the game's world is destructible, which leaves no sniper perch or camper hangout protected.

Also unleashed onto the marketplace this week was Need for Speed: Undercover for 1,600 MS points ($19.99). This racer from Electronic Arts' Black Box studio features an open world, police system, a car customization mechanic, and a character reputation scale.
