Halo 2 (Windows Vista)

Bungie Studios, along with Hired Gun, a division of Microsoft Studios, ported Halo 2 to PC for use on the Windows Vista operating system, as a release title for the "Games for Windows" category. No Mac or XP version is planned as of now. The game was released on May 22, 2007 in the US and was recalled on May 25, 2007 for re-release on May 31, 2007 after partial nudity was found in the game's coding. A patch was released on May 25, 2007 to remove the partial nudity for those people who bought the game before it was recalled for re-release on May 31 and Microsoft sent updated content stickers to retailers who already had copies game of the game before it's May 31 re-release date.

Halo 2 (PC) patches

Main Additions
Halo 2 Vista has been reworked graphically for the PC, including high-definition textures and support for very high resolutions. While the single player campaign does not differ from the Xbox version, if the player has a gamertag for Live, they can earn single player achievements to be displayed on their account.

One of the selling points of Halo 2 Vista is an included map editor. It will include the same programs as previously used in the Halo Editing Kit (HEK). These programs are Guerilla, Sapien and Tool. The full extent of the map editor's capabilities have not yet been made available.

The release date was originally planned for May 8th, 2007. The release date has been delayed for May 22, 2007 (May 29, 2007 in Australia) because the team needs "to make some improvements to the install experience and address other technical issues.". However, release dates have been erratic, as Australia has publicly available copies, and some stores in the United States are selling copies, as well. Microsoft has stated that the release date has been pushed back one final time, making the release date May 31st for the United States.

A new ability pushed by the Microsoft team is a feature called "Tray and Play". It is an attempt to emulate the ability of consoles to instantly play new discs in a DVD Drive without installing them. It allows the end-user to play the game as it is installing.

Multiplayer Additons
Halo 2 Vista, being a release title of Games for Windows, includes support for the Live for Windows system. It intertwines with the Xbox Live system, allowing communication with someone who has an Xbox. Instead of using matchmaking, players will be able to create dedicated servers, which are created with a program that comes with the disc.

Gamertags, which are used on Xbox Live, are also used on Live for Windows. If a player were to have an Xbox Live gamertag, they would be able to log on using that. Otherwise, a free, silver account can be registered for a player. For $50 a year, a silver account can be upgraded to a gold account.
