Halo

Halo is a very interesting and fun videogame. You play as(in most of the series) genetically modified humans known as Spartan II's or Spartan III's. As these spartans, you fight for the United Nations Space Command(UNSC) against an alliance of aliens known as the Covenant. They say that their gods demand the extinction of humanity. In the trilogy, you play as Master Chief Petty Officer Grade III John-117. He discovers ancient weapons called Halo Rings. These things were designed to destroy all intelligent life forms to starve a parasite called the Flood. These hideous beings evolved from a mutated animal known as the Pheru. After destroying Instillation-00 and Instillation-04, he drifts off into space, ending the trilogy. Another trilogy is starting toward the end of the year. It will be called: The Reclaimer Trilogy.
