Nanomachines Explain Everything
Metal Gear Solid has employed various supernatural elements over the years. Given the series' commitment to a realistic world, these elements always stood out as something bizarre but explainable through natural means.
rnFor example, in Metal Gear Solid 4 Solid Snake would encounter an antagonist named Vamp, an ex-member of Dead Cell capable of running on walls at blazing speed, and even standing on water. He would even recover from significant wounds out of nowhere, making him seemingly invincible.
rnVamp, along with a large library of other supernatural elements in the series, would later be explained as the product of nanomachines, microscopic machines that would dwell in the bloodstream of individuals. It was such a ridiculous turn of events that it has remained common joke among gamers when discussing game elements that have no logical explanation.
