It's no secret that the 'Metal Gear Solid V: Ground Zeroes' campaign is extremely short. So when the speed runners decide to see how quickly they can finish the campaign, we found the completion times to be extremely impressive.

So far the average speed run for the Ground Zeroes mission is little over 10 minutes. However, Xearrik has managed to complete the mission in just under 7 minutes; 6 minutes and 48 seconds to be exact.

Although if you are trying to aim for the 'S' rank you might want to not actually kill the guards, put rather hit them with the tranquilizer gun.
