That link is translated through Google's beta Japanese-English translator so, umm, not much makes sense. But there's a video. Not the most graceful thing, and I'd hardly call that "walking", but damn cool none the less (assuming it's real and not CG, which is entirely possible).

Wow! Very cool!

So, do the guns actually work?

Reminds me of mecha from Robotech:
