ZeroBlade: As NAMK mentioned before, the sword is crooked. The blade area itself is very so-so, and reminds me of a chainsaw. The hilt/handle for it however is really nice, the handle makes it resemble a chainsaw even more. I better be careful with that weapon.
ZeroGun: Very futuristic. I recommend comparing this to a real gun to see the accuracy of it. Not bad though.
ZeroRang: It's just a boomerang with special techno-future add-ons. What's the jiff, specialty of it?
ZeroShield: A futuristic shield it looks like to me...though there's nothing special other than a theme change...You can easily replicate it in reality fortunately.
ZeroFist: I don't want to get punched with that. 0_0 Those two blades look very threatening, especially if they're added on to a fist. But they need better anatomy in accords to a real hand.
