I actually ended up cornering him with an assault rifle. What unique camo is that? I don't really care for difficult-to-obtain, game-breaking unlocks. You know, like the stealth camo.
In other news, it just occured to me that Snake Eater is to Metal Gear what Double Agent is to Splinter Cell. Well, except in Double Agent, there's the added difficulty of you dying to like two bullets. They're similar in that previous titles had systems that allowed you to determine where you were out of sight, and where you weren't. But in both these games, that's left up to the player to determine. Which is, of course, a pain in the ass, and the reason I fail utterly at stealth in this game.
Well that, and the fact that once you're spotted, it's practically impossible to hide. Firstly, there just aren't that many good spots, and secondly it takes ages for them to return to normal status. It's way easier to just blast your way through ( or in my case, deliver precise Mk22 headshots and stun grenades. Also, faceplanting people )
