Whether you know your Octacons from your Ocelots, this is the most joyously free-form stealth game there’s ever been. While it may have endured an infamously tortured development – one which saw the game’s ‘true’ ending lopped off – The Phantom Pain remains a towering achievement. What is it, then? Oh, just the greatest stealth adventure of all time… and it’s not remotely close. Flaming unicorns! A sniper who really should be wearing more clothes! The cutest one-eyed dog in the history of games! Metal Gear Solid 5 is not a stealth game you can pigeonhole.
