There is a young blonde kid named Eli in Metal Gear Solid V. Some suggest he is Liquid Snake.
Gamingbolt predicts that this could be the case judging by the Eli’s voice actor’s profile. Eli in Metal Gear Solid V is voiced by a young British actor named Pier Stubbs. His IMDb page shows he’s working on the game.
It’s worth noting Liquid Snake had a British accent in the first Metal Gear Solid game so this might suggest that Eli is indeed him. Bear in mind IMDb pages can be changed by anyone so take this news as a rumor for now.
