Halo: Master Chief Collection is a collection of 6 Halo games released by 343 Industries and Microsoft/Xbox Game Studios, released around the same time Halo 2 celebrated its 10th anniversary. The collection features Halo: Combat Evolved Anniversary (originally released for Xbox 360), Halo 2: Anniversary (remastered for Xbox One), Halo 3 (originally released for Xbox 360), Halo 3: ODST (originally released for Xbox 360), Halo: Reach (originally released for Xbox 360), and Halo 4 (originally released for Xbox 360).
The collection originally released with Halo: Combat Evolved Anniversary, Halo 2: Anniversary, Halo 3, and Halo 4. In a future update in 2015, the option to play Halo 5: Guardians (multiplayer beta) was added in. It stayed in until the new ui update from 2018. On May 30, 2015, Halo 3: ODST was released as a digital purchase-only addon for the collection. On December 3, 2019, Halo: Reach was released as a digital purchase-only addon for the collection.
Players who sign up for the Halo Insider program on HaloWaypoint can gain access to the next build of the game and test new features in development. Incentives for participating can sometimes include unlocking the Halo Insider nameplate, a nameplate that cannot be obtained otherwise.
Halo: Master Chief Collection features 6 campaigns currently for all 6 of its games, depending on if the player has the accompanying DLC.
Halo: Combat Evolved Anniversary
Halo: Combat Evolved Anniversary's campaign has an option that allows the player to view classic graphics (Halo: Combat Evolved) as well as setting classic soundtrack in the game options. The campaign also includes skulls that the player can unlock for gamerscore. Skulls were important for the Xbox 360 version as each skull found unlocked the same skull that can be toggled on or off in game settings, which changes the effects of gameplay.
Terminals were also added into the game which increase gamerscore and add some backstory to the lore. Originally, it was required to have Halo Channel installed to view the terminal videos, but this was changed when Halo: Combat Evolved Anniversary's content was ported to PC.
Halo 2: Anniversary
Halo 2: Anniversary's campaign also has an option that allows the player to view classic graphics (Halo 2) as well as simultaneously changing the music/voice style to classic. Skulls were available in both the classic game and the remastered game. Terminals, however, are new in Halo 2: Anniversary. Similar to Halo: Combat Evolved Anniversary, Halo Channel was required to view the terminal until the port release to PC.
Additionally, toys of various major characters in the game can be collected to increase gamerscore.
Bug: One of the major and most notable bugs for Halo 2: Anniversary is an issue with NPCs starting the map holding only one weapon, in contrast to the classic versions which would spawn the NPCs onto the map dualwielding weapons.
Halo 3's campaign is majorly similar to the Xbox 360 port. For a limited time to celebrate Halo 3's arrival to PC, players could unlock the Acrophobia skull, a skull that required the player to kill 343 flying enemies between the dates of July 14, 2020 and July 29, 2020.
Halo 3: ODST
Halo 3: ODST's campaign is also majorly similar to the Xbox 360 port. The game was added to the collection in 2015 with campaign content only. The open world Mombasa Streets can be accessed via selecting the 'Open World' rally point in the game menu.
Halo: Reach's campaign is also majorly similar to the Xbox 360 port. The game was the last game added to the collection for Xbox One players when it released the same day that the game got its port to PC.
Halo 4's campaign for the PC port was the last addon to release. The campaign plays entirely the same as its Xbox 360 counterpart.
Firefight was a game mode that was not originally in the collection, prior to Halo: Reach's addon release in 2019. The game mode consists of player (or players) who fight off the covenant during each "wave" and may have objectives, such as surviving as long as they can or protecting generators from being destroyed. When Halo 3: ODST's addon was ported to PC, both that addon and the other received the matchmaking option.
The matchmaking game mode allows players to pick which Halo title they wanted to play and the corresponding game mode such as Slayer, Big Team Battle, VIP, Grifball, Infection, Team Action Sack, etc. A voting style system used to exist before the UI update that allowed players to select which gamemode and map they wanted to play on, with the highest voted mode being the one selected for the match.
Players with local lobbies who do not wish to play online with other players can select the Custom Games mode, which allows players to create their own game mode and play on custom maps made with forge mode.
Forge is a game mode that lets players create a custom map that they can use to play in Custom Games. With the release of Halo 3 addon on July 14, 2020, players can now use forge mode to its full potential which allows players to place down any object, including ones that were previously scrapped or hidden.
On June 25, the Season 7 update went public, including a number of bug patches and the addition (and early implementation) of the Custom Edition plugin for the Halo: Combat Evolved Anniversary block. On the same day, 343 Industries also released the new revision of the Halo: Editing Kit (now called Halo CE Modding Tools) which uses original tags from the PC and Xbox version but updated to also support the Anniversary game mode for the single player game mode. Currently only single player campaign maps can be loaded into the collection.
Insider Cut Content
Unfortunately, some content were cut from the game during various Insider flights.
Halo 3: ODST Unused Season Nameplate
A nameplate cut from the game during Halo 3: ODST's flight for PC/XBOX was Sirens, which was a reference to New Mombasa Police Department. It was cut due to players feeling offended by the nature of the plate.
During the mcc - feb flight, two Halo: Online maps were added to the collection: Edge and Waterfall. While Waterfall was included in the final game, only a file labeled s3d_edge.info was left over.
