If you're into first-person shooter games at all, you know there's basically two types of people: Call of Duty or Halo fans. The vast majority actually enjoy playing both games, but everyone has a personal favorite. This video is a classic "What If" style battle, complete with enough easter eggs to keep any hardcore gamer of either franchise happy. Of course, if you're not big on either, you will still enjoy the video... at least if you enjoy highly satirical, violent humor, and come on... how could you not?!
