Halo: Combat Evolved - Development

Development

On July 21, 1999, during the Macworld Conference & Expo, Steve Jobs announced that Halo would be released for Mac OS and Windows simultaneously. Before this public announcement, game industry journalists under a non-disclosure agreement had previewed the game in a private showing during E3 1999, and were reportedly amazed. Bungie Studios later stated an even earlier development build of the game centered on real-time strategy and was "basically Myth in a sci-fi universe."

At E3 2000, the first trailer of Halo was well received. The version shown there differed greatly from the one exhibited previously, marking the first major overhaul in the game's development. At this point, Halo was a third-person action game, in which a transport starship crashlands on a mysterious ring world that orbits a star. Early versions of Covenant aliens appear in great numbers and loot what they can, and war erupts between them and the humans. Unable to match the technologically advanced alien race, the humans on the ring world resort to guerrilla warfare. This version of the game featured Halo-specific fauna, which were later dropped because of design difficulties and the creatures' "detract from the surprise, drama and impact of the Flood."

As rumors had predicted, Microsoft announced on June 19, 2000 that it had acquired Bungie Studios. Halo became an exclusive game for Microsoft's Xbox video game console, and Bungie Studios rewrote the game's engine, heavily altering its presentation and turning it into a first-person shooter. Originally a key element, the game's online multiplayer component was dropped because Xbox Live would be unfinished at the time of Halo's release. While a playable demonstration of the game at Gamestock 2001 was well-received, critics had mixed reactions to its exhibition at E3 2001. The game was released in North America simultaneously with the Xbox, on November 15, 2001; the "Combat Evolved" subtitle was an addition by marketers at Microsoft, who felt that Halo alone was not a descriptive enough title to compete with other military-themed games.

On July 12, 2002, a Halo port for Windows was announced to be under development by Gearbox Software. Its showing at E3 2003 was positively received by some critics, with skepticism by others. It was released on September 30, 2003, and included support for online multiplayer play and featured sharper graphics, but had compatibility issues that caused poor performance. Halo was later released for Mac OS X on December 11, 2003. On December 4, 2007, the game became available for the Xbox 360 via download from the Xbox Live Marketplace for 1200 Microsoft Points.
