2.Unkillable guards unless you have a gun. Why can't snake just slit the throat or snap the neck of that guy he just incapacitated.
3. Top down perspective as standad. I can't kill what I can't see, and the First Person mode is only good while your sparse ammo lasts.
4.Nonsensical characters/story. Sniper Wolf can hold the same position for months? Give me a break.
5.The fact that Snake enters the complex without a single gun or bullet. Why would you infilitrated a compound full of enemy soldiers and not have some weapons on you JUST IN CASE you got in a scrape.
6.Even if you beat down a guard, you let him keep his own weapon. WTFC?
