EDIT By Tanner of FacePunch Studios: I am the original creator of this film.
WARNING: If you haven't played Half-Life, Half-Life 2, or Counterstrike, the following movie will make little to no sense.
Two "headcrabs" get deployed via a canister in the middle east, but after realizing that they are both of a different species, they then have to fight to the death. This movie is 100% stop motion animation, its made up from over 6000 static screenshots played back at 16 fps, its the same concept as claymation, but done with 3D models and ragdoll physics, If you haven't played HL, HL2, or CS, please don't vote zero just because you don't understand it.
This movie has nothing to do with Blocks, Clocks, Locks, or Glocks.
