Great D2 style MGS
Ok, I'll be honest and say that I will never believe this isn't an MGS rip. The character even looks like Snake.
All that aside, I'd say this is a pretty decent game. Given a decent story element, I'd say this could become a worthy tribute to the MGS line. It really does look good, sounds decent, and the soda machines were a nice touch. However, there's not nearly enough expansion in the way things could be done. I got stuck on the second (or third) "dont kill your enemy" stage because I kept getting spotted. The ability to duck behind objects would be very helpful in this reguard (same thing bothered me with the grass, except it was that I didn't need to duck).
Make a sequel, give it a story and multiple ways of performing tasks, give it an MGS title, and put it here on Newgrounds. I'm sure people will enjoy it.
