Pretty Good
I usually don't review, ad I never have the time. Now I saw this, so I figure I had to review. It was pretty good. Very short. I would of liked more action. Instead of the protaganist just killing a soldier, you should of made a boss. That would of been cool.
Also, you are right. Their is a MGS 4 confirmed. Here's an interesting thought for you. Kojima said that he will not make another Metal Gear SOLID. Now, he could make a Metal Gear. Also, Kojima never said he would make a MGS3, yet he did. I think Kojima will either make a game on:
-Raiden, before or after 2
-Grayfox
-Big Boss before or after 3
-Snake after 2
I doubt he will make a remake of 1&2, since that is not his style.
Sorry to bother you with my major fanboism. :P
