Metal Gear Solid 5 has been modded on PC to play entirely in first person mode. Yes, you have been able to look around in first-person for a while, but to play the whole game like an FPS is somewhat of a revelation!
The below gameplay video is of [Metal Gear Solid](movie:593264) V: Ground Zeroes in first-person mode on PC. This latest video is courtesy of Ben Blatcher who has modded the game in such a way that enables the camera to be positioned upon Snakes face as opposed to behind the legendary protagonist.
Watch it through in its entirety and you will spot a few glitches (Snake's body turning invisible) but still a rather neat way of playing the game. Personally I think that the Metal Gear series looks sublime and plays smoother in third person but I am excited about being able to play as snake or having 'Snake eyes'.
If you want to grab and install the mod yourself head here.
