Climb as a group
Plan multiplayer runs, keep the party together, and build a shared history over time.
Closed alpha
Every climb tells a better story together.
RunMates is the multiplayer companion for Slay the Spire 2. Coordinate your party, capture run history, and understand the choices that shaped each climb.

Understand every choice
See profile-scoped statistics, reward options passed, shop inventory left, and run outcomes.
Keep identities distinct
Every local STS2 profile lifetime stays separate, including each participant perspective.
From install to insight
Pair once. Then play.
RunMates Mod reports each player's own local profile. RunMates reconciles those perspectives into one shared multiplayer run.

Privacy by design
Your run data is treated like your data.
RunMates collects only the account information and gameplay telemetry needed to provide the tracker. Device credentials are stored as secure hashes, statistics stay tied to the local STS2 profile that reported them, and raw save-file contents are never uploaded. Save comparison remains on your computer.
