Call of Duty: Black Ops 2 is inflicted with a glitch which formerly affected its series predecessor, Call of Duty: Black Ops; a glitch which lets players crawl at full, walking speed, which is affectionately called "snaking."
As demonstrated in the video above, snaking in Black Ops 2 doesn't require any modification to your console or software; just a deft sequence of button presses. Its practical applications are questionable, though it certainly makes players a smaller target. Also, we imagine watching someone effortlessly gliding sideways across the terrain like a humanoid Roomba is enough to distract a foe long enough to gain the upper hand.
We've contacted Activision to find out Treyarch's plans for fixing the issue.
