Arc System Works, the company behind the Guilty Gear series and the much more recent BlazBlue: Calamity Trigger, has good news 2D fighting game fanatics -- particularly those who enjoyed BlazBlue. They've announced in the latest issue of Famitsu that an update/sequel for BlazBlue called "Continuum Shift" is in development.

Announced to be coming exclusively to the Xbox 360 is 505 Games' sequel to the Guilty Gear franchise, Guilty Gear 2: Overture. Being developed by Arc System Works, this new iteration in the popular series, originally unveiled back in TGS 2007, promises to bring you a sweet blend of action and real time strategy.

 Most, if not all, limited editions usually add around US$ 10 to a game's retail price. Not so with Arc System Works' home console versions of BlazBlue. See, Aksys is taking different approach. Instead of charging a premium for the limited edition, those who pre-order the game will get it for free.

If you're more into 2D fighting games as opposed to 3D ones, then you'll be glad to know that Guilty Gear series creator Arc System Works' BlazBlue arcade fighter has been confirmed for a console release in the latest issue of Famitsu. Details on the console versions after the jump.

Two new Xbox 360 demos have been added to the Xbox Live Marketplace. Unfortunately for gamers in North America, these free demos are not available on the U.S. Marketplace.

First is the Japan-only demo for Guilty Gear 2: Overture. This Xbox 360 title from Arc System Works is the first title in the fighting series to utilize 3D graphics. The demo description describes the game as a mix between the action and RTS genres.

A North American release date for Guilty Gear 2: Overture has yet to be announced. It's currently slated for a November 29 release in Japan.

Next up is the Looney Tunes: ACME Arsenal demo. Available only in European Xbox Live regions, Looney Tunes: ACME Arsenal is a 3d action/adventure title based on the classic Looney Tunes series. Looney Tunes: ACME Arsenal is now out in the U.S. A demo for the game was released on the U.S. Marketplace early this month.

If you're not a fan and thought Arc System Works has been milking Guilty Gear too much by releasing different versions with not much substantial improvements, then Guilty Gear 2 Overture may catch your attention. As Japan's favorite fighting game series enters the next-gen scene, it also transforms into an action game for Xbox 360. Take a peek by checking out the trailer shown at Tokyo Game Show 2007.

Guilty Gear and 3D in one sentence would've sounded ridiculous a couple of years ago, but it happened. Sol Badguy will take up arms once more, but not in glorious 2D.

Are you ready? Followers of Guilty Gear would cringe at the thought of the series breaking from its roots, but many would feel guilty pleasure after watching the video below. So, without further ado, let's rock!
