Halo: Combat Evolved is a First Person Shooter science fiction video game, created by Bungie Studios, which was at that time a subsidiary of Microsoft Game Studios. It was released for the Xbox game console on November 15, 2001 and is backwards-compatible with the Xbox 360. It is one of the most popular video games for the Xbox, with over five million copies sold. Its sales are rivaled by its sequel, Halo 2 and later by Halo 3.
It was made available as an Xbox Original title on December 4th, 2007 for download on Xbox Live Marketplace for 1200 points.
Halo: Combat Evolved is also available on PC.
Halo's gameplay was characterized by several features which set it apart from less acclaimed first-person shooter games at its time:
- Storyline execution: Halo's gameplay and storyline have been known for being tightly interwoven, delivering a convincing manner being consistent with the flow of the game.
- Vehicular Incorporation: Despite being a first-person shooter, Halo includes the option for players to control multiple vehicles, both ground and air.
- Weapons system: Halo's new weapons system was unique in two major respects; the first being its allowance of only two weapons to be carried at any given time (forcing the player to make trade-offs as they progressed throughout the game), and the second being its implication of a separate button used for the throwing of grenades.
- Artificial intelligence: Halo's AI was quite sophisticated for its generation. With a brand new, advanced AI system, actions performed by the AI such as panicking after the death of a superior, diving out of the way of an oncoming vehicle, or even taking cover from explosives or suppressive fire, helped Halo stand out from the rest of the first-person shooters being released at the time.
