If there's any one game that embodies the general notion of "What the holy f**k was that?!", it's Metal Gear. Before this list gets underway I have to point out everything within is said with the utmost love and reverence for the source material as possible. MGS damn-near changed the world as the first Hollywood-level blockbuster gamers had ever got their hands on, and from then on out creator Hideo Kojima has released consistent masterpiece after consistent masterpiece, the end result being one of the most enjoyably convoluted and bat-poop ridiculous cavalcades of overblown characters and plot twists in gaming history. Like every artistically-minded creator who dares to dream, they pride themselves on pushing the boat out, and although 1998's Metal Gear Solid tends to be the most immediately recognisable, not 13 years prior Kojima was straight-up inventing the stealth genre by accident. What started as out-the-box thinking as Hideo elected to make Snake evade guards rather than gun down scores of them, turned into an ethos for the franchise as a whole. As such, across the last 28 years we've had everything from supernatural ghost-soldiers to half-naked snipers, nanomachine-powered vampires and kinky cardboard box sex. Think that sounds crazy? You ain't seen nothin' yet. Note: The Phantom Pain spoilers will be flagged.
