Japanese prototype of Axis a.k.a. Final Zone. If you look at the screenshots on the US retail box of Final Zone, you will see differences in the interface and a few other things. I am not sure if this version is the one shown in the early photos, but it's possible, given that this is a Japanese version. Still, we know some of these are just finished versions on sample cartridges for review. I asked the seller if there were differences and all he said was, "Since it's a prototype, sure", but like I said, that doesn't say much. I am curious about it, though.
