I picked one of these sets up as an impulse buy. I have no idea the backstory on this thing. What caught my eye was the absurdity of it. They go together pretty good. Instructions are very BanDai-ish. I turned mine's legs around and will either build them as some sort of recon walker or a training walker for larger mechs. I've never been a big Hasegawa kit fan but I'm checking their kits out more lately.
