Metal Gear Rising Revengence is set in the year 2018 which isn’t that far from our current year. As mentioned previously, Rising is known for it’s ridiculous and almost campy style of action. However the Metal Gear series has been known to take already existing technology and apply it with some tweaks in the Metal Gear universe, Rising is no different.
In Metal Gear Solid 3, the Shagohod is a variant based on the real life Russian tank, Shnekohod. The Shnekohod is a screw-propelled tank that’s able to go on snow and swamp terrains. The whole concept of the Shagohod mimics that of the Shnekohod, a tank that will go anywhere.
The evolution of the Shagohod in Metal Gear Solid, is Metal Gear Rex. The main evolution was that it had legs as opposed to being a screw propelled tank. While there is currently no real life version of Metal Gear Rex, there has been some development regarding a tank with legs, the RHex robot. There is some interest in the whole concept of a tank with legs.
“The Army Rapid Equiping Force has already bought four to use in Afghanistan, particularly to climb in and out of ditches and culverts where insurgents love to hide roadside bombs but where the wheel-driven robots used by most bomb squads cannot go.” – Sydney J. Freedberg JR.
Another example of Metal Gear technology already existing in real life is the Fulton surface-to-air recovery system from Metal Gear Solid 5. The Fulton system is used by the CIA, United States Air Force and United States Navy to recover ground operatives through the use of an aircraft. According to the official CIA website:
“Fulton first used instrumented dummies as he prepared for a live pickup. He next used a pig, as pigs have nervous systems close to humans. Lifted off the ground, the pig began to spin as it flew through the air at 125 mph. It arrived on board undamaged but in a disoriented state. Once it recovered, it attacked the crew.” – CIA
A prominent example of futuristic technology present in Metal Gear Rising are prosthetic limbs, or rather bodies. Prosthetic limbs themselves aren’t exactly new in this day and age. The earliest form of a prosthetic limb is a false foot believed to be roughly 3000 years old. The whole concept of upgrading your body through prosthetic limbs isn’t that far off either. While the main protagonist of Metal Gear Rising, Raiden is able to fight giant machines and has crazy fast reflexes, real life prosthetic limbs such as the Bebonic hand comes with some enhancements that are useful for self defense. As stated in this article:
“The hand may be impressively lightweight and streamlined, but it can pack a punch. Wallace explained that they have to make the fingers stronger than human fingers owing to the lack of biofeedback. While you’d never lean your entire weight on your little finger—it’d hurt—you could put a lot more pressure on the prosthetic without realising it.” – Kevin Evison
The main piece of technology that’s responsible for all the crazy and insane stunts pulled off in Metal Gear Rising is nanomachines. Nanomachines in Metal Gear Rising is the source of all the powers the characters have. In real life however rather than having a combat-focused function, they’re used for medicinal purposes. While still very early in the development stage, the possibility of using nano-particles to feed medicine into a person’s brain is being explored. These nano-particles can also be remote controlled to guide the nano-particle to it’s destination. As stated in this Motherboard article the nano-particles can be used to fight brain tumors. “With magnetic heating of magnetic nanoparticles that are attached to the BBB, we can evaluate the efficacy of orally administered chemotherapeutic drugs such as temozolomide on this tumor.”
Despite how detached the Metal Gear series can be from reality, there is a surprising amount of technology that’s achievable in our current day and age. Although not to the insane level of taking down colossal war machines, not yet at least.
