PS3 = PS3

Re = Remake of the first Metal Gear

36 = 3rd of june (6) 2009

now as for the pictures.

that is Obviously Big Boss/Naked Snake the eye patch being on the right and the berret hinting outer heaven

now as for this picture

(Thanks to leo-j)

that is NOT Raiden, it is Null / Gray Fox / Frank Jaeger

Discuss?

I don't see a 9. I see a 0 though ;)

and the rain meaning that Big Boss would be featured in Heavy Rain

havent seen a 0

 Edit: Looks like a 0 in the magazine? hmm...

@ nojustno
Where was there a "0"

Are you guys even looking at the scan?

where is the 0? i dont see it. and stratch the 9 xD i dont think that is there.

Edit: oh i see it now.

a 0, right?

That is definitely Raiden.

Look at the character's eyes. It is Raiden. Remember the fuss about his effeminate eyes when MGS2 came out? Kojima never remodelled his eyes, he made them darker. The eyes are of Raiden for sure.

Also, "Militaires Sans Frontieres" is a completely new institution in the Metal Gear saga. It means "Military Without Boundaries" which might indicate the happenings of the war machine after the downfall of PMC's in MGS4.

As for the Snake like character... Big Boss died for good in front of our eyes at the end of MGS4. As another poster has said before, it might be Solid Snake who somehow found a reversing cure for his rapid aging.

I hope for, and want it to be, a sequel.
