New Guitar Hero On Tour: Modern Hits character Calista Valenz has now been unveiled by Activision, and here she is:

Calista Valenz is tough as nails and sweet like candy, with a smile that can melt any man’s heart. Her motto is, “Fake it until you make it,” and she has a habit of telling strangers today is her birthday. Calista once volunteered to spend a week in jail for charity and was put behind bars on a Monday, got bored, and somehow escaped that Tuesday. She spent a month running from the law, even though no one was looking, and hid out at a night club. The rocker pretended to be a lead guitarist, and during her first show, a record promoter told her she was a no talent hack. She smacked him upside the head with a sausage and dumped spaghetti down his pants, all with a smile. He stood up and immediately signed her to a lifetime contract.

Guitar Hero On Tour: Modern Hits will be out on the Nintendo DS in the summer, and will feature tracks from such top aritsts as Fall Out Boy, Coldplay, and Weezer. 25 master tracks will feature in total, and this will be, without doubt, the best handheld Guitar Hero game ever.

The European release date for Red Faction Guerrilla for the Xbox360 and PS3 formats has been moved forward by a week, and the game will now be available to buy as of June 5th.

A singleplayer demo is now available on the Xbox Live Marketplace and Playstation Network, so if you’re interested in playing the game now then definitely do give that a download.

Unlike previous titles in the Red Faction series; Red Faction Guerrilla is a third-person shooter (TPS) as opposed to a first-person shooter (FPS), and is to be the third released game in the Red Faction series to date.
