I'm not even sure if I mentioned it in my review below, but Prototype was my favorite of the 7 shorts. And here is why. Friggin awesome. The suit itself was basically an XV8 with a Mjolnir-esque helmet attached. You get a good view of the face and the very "burst cannon" looking machine gun the prototype wields.
The second photo I like because it really looks like it has a burst cannon, missile launcher, and drone controller, doesn't it?
