Some quotes from 1up hands-on:
"It was truly a surreal, unprecedented experience...not even the three days I spent sequestered within Konami's U.S. office to review MGS3: Snake Eater back in 2004 could compare. In Nasu, I found it incredibly easy to sever all ties with the outside world and fully immerse myself in the dense MGS mythology for 72 unforgettable hours."
"But as special as this experience was, it also brought with it a bizarre burden -- keeping all those shocking narrative revelations and massive, life-ending spoilers under wraps wouldn't be easy."
"This game deserves a thesis, not a moment-by-moment walkthrough of what you'll be experiencing yourself come June 12. So if you're a MGS fan who's already sold on this game, I suggest avoiding any and all media that drops between now and its launch. The surprises it has in store for you simply shouldn't be spoiled."
"Since MGS4's gunplay feels better than ever before, it's fitting that Konami has crafted a wildly customizable new weaponry system to maximize your firearm fun."
