Unconfirmed history [ ] The following information has been detailed in official Konami-licensed media, written by various external authors. Its status in the Metal Gear canon is unconfirmed. [?]

Life isn't just about passing on your genes. We can leave behind much more than just DNA. Through speech, music, literature and movies... what we've seen, heard, felt ...anger, joy and sorrow... these are the things I will pass on. That's what I live for." ―Solid Snake [src] If you ask me, there's no happiness to be found in death... no peace either. I'm leaving here alive." ―Solid Snake [src] Snake is an unique recruitable character in Metal Gear Solid: Portable Ops Plus, under the Old Snake codename, and featuring his aged appearance from Metal Gear Solid 4. In addition, because Portable Ops Plus was released before Metal Gear Solid 4, this also marks the first time that Solid Snake appeared as Old Snake in terms of the overall series. When he is recruited, Campbell remarks, "Some old guy joined our team. Kinda reminds me of Snake" (referring to Old Snake's obvious similarities to his father, Naked Snake). [113] Big Boss (Venom Snake): Solid Snake! I've been expecting you... ...I am the supreme commander of the FOXHOUND unit... And... The leader of the fortress of Outer Heaven, Big Boss! I gave this mission to you, a rookie, thinking I could use you to fool the rest of the world... But you were too good. You went too far! Solid Snake! I'm not going down alone. I'm taking you with me! Prepare to die!Pliskin: The B-C connecting bridge. // Raiden: We need to get there. Can you handle it? // Pliskin: I need a few more minutes. // Pliskin is pretending to be worse off than he is. He intends to go separate ways from Raiden, then keep him under surveillance to ascertain if he can be trusted. Explanations to come later (standard radio). It is first revealed that Big Boss is the "father" of Solid Snake in Metal Gear Solid. Snake tells Naomi Hunter that Big Boss had told him of this prior to his defeat in Zanzibar Land. It is commonly assumed that Big Boss relayed this information to him immediately prior to their final battle in Metal Gear 2, though the only detail made clear is that Snake knowingly "killed" his own father at that time, with only himself and Roy Campbell being aware of this. [103] During Raiden's first meeting with Pliskin in Strut B, the player has the opportunity to directly interact with him:

At first, Snake was a Green Beret but then he was later initiated into High-Tech Special Forces Unit FOXHOUND while it was under the command of Big Boss. Snake became a war hero for stopping potential nuclear catastrophe three times by repeatedly disarming and destroying the latest incarnation of Metal Gear. Although Snake does not actually appear in Portable Ops due to it taking place two years prior to his birth, he was briefly alluded to by Elisa/Ursula while dying, where she explains the future to Big Boss.If the player inputs the Konami Code on the game clear screen, Solid Snake will be heard saying either "What do you think you're doing!?" or "STOP FOOLING AROUND KID!" Snape's Japanese voice actor, Takaya Hashi, provided the voice of Skull Face in the Japanese version of Ground Zeroes.
