A new mod has been made available for the PC version of Metal Gear Solid V: Ground Zeroes. It takes all that tactical espionage action normally set in the third-person point of view and moves it to first.
You can nab the mod on Nexus Mods in the source link below. It arrives with a few known bugs, though nothing absolutely game-breaking. This doesn’t look like a tough mod to get working, so if the video above piques your interest in going first-person on PC with Metal Gear Solid V: Ground Zeroes, go for it.
