How Hunt Showdown MMR Actually Works (OpenSkill)

What Crytek officially confirmed

In the official Developer Insight: Network & Matchmaking (November 2024), Crytek stated the system clearly:

• Algorithm: MMR uses a modified version of the OpenSkill algorithm, which includes a certainty variable that adjusts over time.
• Inputs: MMR is determined by in-game performance — not playtime, rank, or prestige. Specifically, kills and deaths weighted against the skill of the players you fight.
• New vs veteran: When you are new, your rank fluctuates more often; as the system learns your skill, it stabilizes and changes less radically per match.
• Modifiers: Team composition and win/loss streaks are considered, but these do not alter your actual MMR — they only influence how matches are built.
• Star system: Creative Director David Fifield confirmed the 1-6 star framework, describing it as reflecting “your frequency of success” rather than a fixed Bronze-Silver-Gold ladder. The 2.9 MMR Decay system is a separate, temporary modifier for returning players and does not change this base.

What is community estimation (not official)

Third-party sources publish specific MMR point ranges — commonly something like 1 star = roughly 0-2000, 6 stars = roughly 3000-5000, with most players clustered around 2600-2800 (predominantly 4 star). Crytek has not published the exact numerical mapping, so treat any specific point-to-star conversion as a community estimate, useful for orientation but not authoritative. The star display in your lobby and profile is official; the underlying number behind it is not shown to you.

The SBMM toggle

A “Skill-based” tick-box exists in Bounty Hunt and Quickplay lobbies. It is enabled by default and cannot be disabled for trainees and random groups. This is the practical lever you control; the underlying OpenSkill rating is not.

How to read your lobbies

If you are a new or returning player, expect volatility — that is the certainty variable doing its job, not a bug. If you are an established player, your lobbies reflect your recent performance against opponent skill, and team MMR is averaged across your party. The 2.9 hidden-info changes and the death-attribution series (audio, positioning, timing, loadout) matter far more for your win rate than the star number next to your name.
