Brilliant though it is, Metal Gear Solid 5: Ground Zeroes is quite short considering its asking price. But quite how short depends on whether you know what you're doing or not. In fact, this video shows the game's main mission being completed by our own Guides Editor in just 7 minutes. That results in an S Rank, so feel free to use the technique for your own Trophy-hunting endeavours.
Of course speedrunning is not an indicator of actual game length so don't think your money will only get you 10 minutes of enjoyment. Several staffers around the office have racked up 16 hours in Camp Omega already. That said, it is apparently possible to get the completion time down into the 5-minute margin. How fast can you do it? Let us know in the comments.
