Has anyone seen this japanese metal gear solid 4 ad?

Warning while in no way related to the plot line it might be. So if you don't want to get spoiled don't go there.It's an energy drink ad but there is something special about it. Hides behind couch.

*EDIT
Or the octocamo made he look young to simulate feeling young again.
I think that makes more sense, but who knows.
