Inspired by a post on the Halo subreddit showing player rankings in different multiplayer playlists in Halo 5 I decided to do something similar. I used the Halo 5 API R package I wrote a few months ago got to work collecting as much data as I could from users.
public API has several limiting factors. First is that there's no easy
way to simply get a large list of users currently playing Halo.
Microsoft doesn't make public player activity numbers public so having
easy access to this would probably be against their intention. To get
around this I looked at my recent game history, and took all the names
of the players of my opponents. Then looked at all their recent game
histories. Quickly I was able to get a list of a little over 17,000
unique names that played at least some form of matchmaking.
second limiting factor is that Microsoft only allows 1 request per
second. This isn't really a huge hurdle as I just left it running
overnight to gather the data. It would be nicer if there was a faster
Anyways here are some results from the
Team Arena, Slayer, and SWAT playlists. Keep in mind that when this data
was gathered it had only been about 10 days since the February season
went live. I'll try to do something like this again at the end of the
month to see if there are any major changes.
interesting thing is the large percentage of players currently in onyx.
I think this is likely due to my small-ish sample size of just over
7000 players for Team Arena, and because it's still early in the season.
As the season goes on the more casual players will finish their
placement matches and the relative amount of onyx players will probably
I've also included a boxplot showing win
rates of players in the different ranks. Nothing really surprising; as
players rank increases so does their win rate. Though from my
understanding the matchmaking system should try and give players a close
to 50% win rate, so again, perhaps this will even out as the season
I hope you enjoyed these. Comments and suggestions on what other kinds
of data from Halo 5 might be interesting are definitely welcome. What I
really want to do is make some heatmaps (still) but 343i seems like they
do not want to make the necessary data to do this available. Maybe
