Whew, good to see this thread is thriving again, didn't want to get tagged for necro-ing. Anyway, I know it's not possible with pep but if someone were to construct an Octocamo Suit worn by Old Snake in MGS4, that'd be badass. Maybe posting a tutorial to guide the rest of us would be possible.. *drool*...
and yes, I am aware that a Raiden suit is being made. Not really the same, but pretty awesome anyway.
