Things open up in hour two of Metal Gear Solid 5. We're out of the hospital, and we're no longer crawling around with a hook for a hand. Big Boss comes into his own as the game begins to allow the player to do the same: he's now a fearsome soldier with a bionic arm, a little bulkier than the Solid Snake of yore and every bit the grizzled super-soldier we've been told to expect. He cuts a fine figure there in the dust of Afghanistan.
