If you're of the opinion that the Xbox 360 doesn't have nearly enough giant robots smashing each other to bits, then you may be interested to know that an Armored Core 4 demo has been released in Japan. While most of our readers aren't from Japan, that doesn't mean they can't sample the robot goodness for themselves. It just so happens that there is a fairly simple way to grab Live content from other regions -- not that we condone that sort of behavior. No, we couldn't condone that sort of thing. It would be out of the question for us to, say, post a link to the method for circumventing region lockout.
So, if you've been hungering for some giant robot destruction, you'll just have to look elsewhere (wink wink).
