Two YouTubers believe there’s a hidden MMR system in Modern Warfare

Drift0r and The eXclusiveAce tested six accounts in total for the Call of Duty experiment.

A pair of YouTubers have concluded that Call of Duty: Modern Warfare has a hidden skill-based matchmaking system after collecting several hours worth of data in game. Drift0r and TheXclusiveAce have published their findings online after testing six accounts of different skill levels.

Based on the raw data, which you can view for yourself here, the two YouTubers concluded that Call of Duty matchmaking does not prioritise skill over matchmaking, players with high stats are not paired together, but players with similar ranks are.

Despite that, the duo believe there is some sort of hidden matchmaking ranking system in Modern Warfare, even though they’re not matched based on their KD/R, win/loss ratio or score per minute. But based on their experience from playing on different accounts, both YouTubers experienced a notable change in skill.

“There appears to be a hidden MMR system in Call of Duty,” Drift0r says in his video, which you can watch below. “This year I personally requested other accounts to play on so I could feel the difference between them and my experience were that every account I played on had increasingly skilled players.

“The difficulty changed massively from an experiential point of view but not from a mathematical point of view, which really doesn’t make any sense to me, and the only way this makes sense is if there is a hidden ranking system that we can’t see from public stats.”

And if higher skilled players are being matched against one another in this hidden system, their in-game stats are likely to drop as they face harder competition. Regardless, it would be good if Activision could tell us how the matchmaking works, and if it’s skill based or not. For now, we’ll have to keep guessing.
