video game developed by Bungie Studios. The first game of the Halo series, it was released on November 15, 2001 as a launch title for the Xbox gaming system, and is considered the platform's "killer app." With more than five million copies sold worldwide as of November 9, 2005, Microsoft released versions of the game for Microsoft Windows (developed by Gearbox Software) and Mac OS X in 2003, and the surrounding storyline was adapted and elaborated into a series of novels. The game was later released as an Xbox Original for download onto an Xbox 360 HDD.In Halo's twenty-sixth century setting, the player assumes the role of the Master Chief, a cybernetically enhanced "SPARTAN" super-soldier. The player is accompanied by Cortana, an artificial intelligence who occupies the Master Chief's neural interface. Players battle various aliens on foot and in vehicles as they attempt to uncover the secrets of the eponymous Halo, a ring-shaped structure. The game has been called "easy to learn'' and has been praised for its "engaging story.

As a first-person shooter, Halo: Combat Evolved has a gameplay fundamentally similar to that of its peers, focusing on combat in a 3D environment, and taking place almost entirely from a character's eye view. The player can move around and look up, down, left or right. The game features vehicles, ranging from armored jeeps (Warthog) to tanks (Scorpion), alien hovercraft (Ghost) and even an aircraft (Banshee), all of which can be controlled by the player. The game switches to the third-person perspective during vehicle use for pilots and mounted gun operators; passengers maintain a first-person view.

The player character is equipped with a damage-absorbing energy shield, in addition to hit points. The shield's charge appears as a blue bar in the upper-right hand corner of the game's heads-up display. When the shield is fully depleted, the player is highly vulnerable, and further damage reduces the character's health level. Critically, however, the shield will recharge if no further damage is sustained for a brief period.
