Halo: Combat Evolved, is the best action game and is also referred as Halo: CE, or simply Halo. It is a first-person shooter video game published by Microsoft Game Studios. The game was later released as an Xbox Original for download onto an Xbox 360 HDD. Halo is set in the twenty-sixth century, with the player assuming the role of the Master Chief, a cybernetically enhanced super-soldier. The player is accompanied by Cortana, an artificial intelligence who occupies the Master Chief's neural interface. Players battle various aliens as they attempt to uncover the secrets of the eponymous Halo, a ring-shaped artificial world. The game has been called 'easy to learn', and has been praised for its 'engaging story'.

Many game magazines have praised Halo as one of the best and most important games of all time. The game's popularity has led to labels such as 'Halo clone' and 'Halo killer', applied respectively to games either similar to or anticipated to be better than it. In addition, the game inspired and was used in the fan-created Red vs. Blue video series, which is credited as the 'first big success' of machinima (the technique of using real-time 3D engines, often from video games, to create animated films). Two sequels, Halo 2 and Halo 3, a side game, Halo 3: ODST, and a prequel, Halo: Reach, were released in 2004, 2007, 2009, and 2010, respectively. A remake, Halo: Combat Evolved Anniversary, was released in 2011, on the 10th anniversary of the original game's release. Halo 4, a planned sequel by 343 Industries, is currently in development.

Halo: Combat Evolved, also known as Halo 1, is a very successful first person shooter (FPS). In Halo: Combat Evolved, as Master Chief Petty Office John-117, one of the remaining super-soldiers of the Spartan II project, you take on the Covenant alien race in a holy war which might determine whether or not the human races survives. The controls in Halo: Combat Evolved are as good as any FPS and you'll immediately feel at ease blasting away alien intruders, launching grenades and strafing behind pillars and walls. As you proceed through the game you are joined by other Spartan II super soldiers who help you annihilate the aliens. The graphics are a little outdated, after all this is a game released in 2003, yet you won't suffer any lags and scenery and little details are on the whole satisfactory. At least it won't distract you whilst on your various missions.

One of the great features of Halo: Combat Evolved is the number of vehicles and weapons at your disposal like the Warthog or Banshee. The artificial intelligence (AI) in Halo: Combat Evolved is well developed and the three levels of difficulty should keep you well occupied. Another great feature in Halo: Combat Evolved is the multiplayer, with classic deathmatch, capture the flag and king of the hill games great fun among friends.

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 and tanks to alien hovercraft and aircraft, many 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 is applied directly to the character's health level. Critically, the shield will recharge if no further damage is sustained for a brief period. This regenerating shield is a departure from FPS games of the time which force the player to rely upon pickups of health and armor. Halo's arsenal consists of weapons from science fiction. The game has been praised for giving each weapon a unique purpose, thus making them useful in different scenarios. For example, plasma weapons need time to cool if fired too rapidly, but cannot be reloaded and must be discarded upon depletion of battery. In contrast, conventional firearms cannot overheat, but require reloading and ammunition.
