It says a lot about the Metal Gear Solid series that the best description of its follies I've ever seen comes from an Irish comedian.

The man on stage is Dara O'Briain, who as you can see, is such a big fan of the Metal Gear series (and plenty of other games!) that he devotes a gag in his latest show to the quirks you encounter trying to sneak protagonist Snake around a map.

A warning: the man is Irish and is excited, so yes, there is profanity. Best keep the volume down if the boss is around.
