This game is very short, but it is very good! Quality over quantity as they say. I completed the mission in about 70 minutes, but the level was really well designed, having multiple ways to get through obstacles and generally being as creative as you would expect from a Metal Gear game. The story tackles subjects that are still very taboo in the video game world, and is pretty disturbing to follow through the different tapes you get in the game! It also adds some pieces to the gigantic puzzle that is the story of the Metal Gear franchise. It's too bad that this used to cost so much money, because this single level is on par with the levels in The Phantom Pain!
