Ben Blatcher, the one playing the mod, writes about the mod and his experience playing it. 

Throwing in a different perspective to a game isn’t something new, it’s been done by modders for a variety of games and recently it’s been done by Rockstar Games for GTA V, but the novelty of the perspective change is always interesting and welcome.

PC gamers and owners of Metal Gear Solid V: Ground Zeroes can play this mod right now. The mod still has problems and bugs but the experience is still one that gamers should try out.
