MMR—matchmaking rating—is essentially a measure of skill used to ensure fair matchups in multiplayer games: Putting together players with similar MMR helps avoid the vicious beatdowns that can occur as a result of randomized matchups through server browsers. It's not something that games typically display to players—actual MMR ratings are often invisible data points that exist behind the scenes—but a group of Halo fans recently figured out how to track individual player MMR in Halo Infinite, and discovered how playing the game in casual modes can actually wreak havoc on your ranked experience.
The post explaining the process on Reddit says that while team-based data on performance and average MMR is provided by 343's servers, individual MMR data isn't included. Free-for-all games, however, essentially count each individual player as being on their own team, so the data the team MMR data servers spit out can be linked to an individual player in an FFA game.
«This means that with the way the data flows from Halo Infinite now, each time you play an FFA game, you can see what your MMR is as of the moment you complete that game,» redditor donutmonkeyman wrote. «Right now this is the only way we know how to find this value, as we don't think it's something 343 wants folks to get a hold of.»
So, this:
Becomes this:
It's all quite arcane, and knowing your exact MMR isn't especially useful when the game already gives you a rank between Bronze and Onyx, but its potential value as an analysis tool is where the discovery gets really interesting. The post notes that some players on the Halo subreddit have complained that doing well in bot-based playlists is artificially inflating their MMR, forcing them to be thrown into high-skill
