Call of Duty 4 gunshots mixed into a delightful little musical number, accompanied by a seizure-inducing video of the source material. Largely unremarkable, though there are a few vaguely compelling musical themes as the last third of the mix begins.

The "Fewest Portals" challenge for Chamber 18 performed using only 5 portals, though a wallclimb exploit is used to effectively skip the final chamber.
