Armored Core for Answer, the thirteenth title in From Software's giant mech love fest, is preparing to stomp onto North American shores later this year. Ubisoft is set to publish the laboriously-titled game, which will unload onto both the Xbox 360 and PlayStation 3 in September.

Armored Core for Answer follows 2007's Sega-published Armored Core 4, and promises to once more let players slip behind the controls of a giant modular war machine, with "epic" boss fights, "seamless" 2-player co-op and 7-player competitive modes promised as well. Much like most games that come out of Japan, Armored Core for Answer pits rebels against a malevolent megacorp with the fate of the world, not to mention precious customizable parts (130 new, 400 total), hanging in the balance.

Sony has sent word of their new offerings for the US PlayStation Network today. Most importantly for racing fans, Gran Turismo HD Concept will be upgraded for free to version 1.2, which enables force feedback through Logitech steering wheel peripherals. (European gamers have been enjoying GTHD 1.2 since the console's launch in the region.)

The Grand Theft Auto IV trailer is also available for download in high definition, as is the Armored Core 4 demo. Microsoft's Peter Moore, proud that Xbox Live got the GTAIV trailer up before Sony, has added yet another tattoo on his arm to add to his collection of AAA-titled inkings.

All of the content will be available free of charge and should be online sometime today.

[Update: It's the Armored Core 4 demo, not trailer, that is released today. All parties responsible for the error have been thoroughly sacked.]

Fans of giant battling robots, rejoice! A demo for Armored Core 4 has been released onto Xbox Live. Also rejoicing: Fans of not paying $60 for games with uniformly mediocre reviews. Xbox Live's Major Nelson spilled the giant, robotic beans yesterday on his official blog that the strictly single-player affair was available for download and contained three -- count 'em -- three single player missions.

Oh, and those of you who don't like to get involved with a new franchise until it reaches at least its 10th iteration, giving it time to age like a fine wine, can download with confidence. It may say it's the fourth in the series, but it's a little more like the bajillionth.

It's an old-fashioned PS3 versus 360 graphics showdown in today's video pick, with GameTrailers running a side-by-side comparison of Armored Core 4. Which version of this mech title looks best? Judge for yourself after the break, or visit the HD version -- it doesn't embed like the SD file -- on the GameTrailers site. Let the scrutiny begin!

Xbox 360 will receive some love from an important Japanese franchise in early 2007. From Software's Armored Core 4 is scheduled to arrive on Microsoft's console on March 22 -- it's already available on PlayStation 3. The deal will be sweetened by a "special movies" DVD and art booklet, available to reservation makers.

Sega, which has signed on as publisher, plans to bring both versions of Armored Core 4 to North America. The Xbox 360 release marks the first time the Armored Core series will be available on a non-Sony platform (with the exception of mobile phone spin-offs).

It's said that the rats are the first to abandon a sinking ship. While not rats, publishers are beginning to abandon the PS3 after its less-than-impressive launch and news of production woes. Three titles have pulled up stakes and moved to the Xbox 360 (as cross-platform).

Koei, long time PlayStation supporter (and company frequently billed as key support to win the generation) has pulled Fatal Inertia and Blade Storm: The Hundred Years' War from the PS3 exclusive list and plopped them squarely into the Xbox 360 camp. Another PlayStation staple, the Armored Core series, is also coming to the white box in the form of Armored Core 4.

Sony is going to be in for a difficult battle if key players keep moving over party lines; Microsoft is doing far better coaxing exclusive content over to the 360. If Sony continues to lose its differentiation, why should gamers continue to shell out up to $200 more just to play the same games? Enjoy this machine translation for those who can't read Japanese.
