343 Industries has delayed the Halo: Reach PC "FireFlight" that was originally planned for July due to "severe blocking bugs," meaning that those hoping to try out the first game to be released in the upcoming Halo: The Master Chief Collection for PC will have to wait a bit longer.

Ring 0 - Ring 0 is made up of internal studio folks. This is a combination of the 343 Publishing Team, 343 Pro Team and developers within the studio who participate in playtests we hold regularly on the content we are aiming to flight. If serious bugs are found in Ring 0, it does not progress to the next ring and will not make it outside of the studio. The team goes back to the drawing board to address any issues that are identified. If no serious issues arise, however, we move to Ring 1.

Ring 1 - Ring 1 is made up of external partners that work closely with the studio (many of which have for quite some time). This allows us to work with players who know Halo content and are spread around the globe testing our various pipelines and supporting services to ensure the experience is fully functional. If any major issues are found here, it can cause a reset all the way back to Ring 0 if severe enough and warrants the build to be properly vetted and tested again. If all is well, this moves on to our next group of external partners.

Ring 2 - Ring 2 is made up of even more partners of various skill sets that help test our builds in unique and interesting ways to ensure that we are providing the best experience for all varieties of users who are invited to test flighted content. If nothing show stopping is found here, it then will make the jump to our final Insider’s ring, Ring 3. As with all previous rings, if any major issues are found here, it can cause a reset all the way back to Ring 0 if severe enough.

Ring 3 - Ring 3 is the Halo Insider user group that is determined based on KPIs (Key Performance Indicators) the team sets for wanting to test in any given flight. This audience could be hardware based, experience based, locale, or any specific metric the team is looking to validate or stress at any given point as these flights are not BETAs, but indeed are at-scale tests to validate the state of the build to assess functionality and release readiness.

343 Industries published a blog on HaloWaypoint.com to update Halo fans as to why the planned flighting hasn't happened yet and what these "blocking bugs" are.Blocking Bugs are issues that "are deemed severe enough to prevent a flight from functioning as needed." As development proceeds, a flighting build must pass certain tests called "Rings," without these blocking issues, before it is made available to Halo Insiders.There are four rings in total and each build must past through the first three rings before its released to Halo Insiders. Descriptions of each ring can be found below;At the time of publish of 343's blogpost, the team has completed Ring 1 testing and has moved on to working through five Ring 2 blockers and fifteen Ring 3 blockers. The five current Ring 2 blockers are as follows;343 isn't giving a date for when this next flight will be available, as dates change as the project progresses and issues come and go. However, it promises it will be "ready when it's ready."343 is planning on flighting Firefight Matchmaking and PvP Matchmaking for PC and "the goal is as soon as the Xbox One version of Halo: Reach is ready to go [it] will flight that."As a small solace, 343 has provided a work in progress render of the Elite Minor in Halo: Reach's armor customization screen. Halo: The Master Chief Collection for PC and Halo: Reach being added to MCC for PC and Xbox were revealed earlier this year. Each game in Halo: The Master Chief Collection PC will be released one-at-a-time in chronological order of the canon story.On Xbox One, Halo: Reach's multiplayer will be available for free for owners of the Master Chief Collection, while the campaign and Firefight mode will be available for purchase. However, Xbox Game Pass subscribers will get all of Halo: Reach for free. Halo: Reach will arrive on PC as a complete package to the MCC.
