Teamfight Manager 2 patch 0.5.0_beta4 notes

Updated 2026-07-01 · based on v0.5.0_beta4

Quick Answer

Fourth 0.5.0 beta build. Adds Champion Mastery, where every player has per-champion mastery values and receives stat bonuses from them; improves Composition Test so tactics can be configured; and adds Deathmatch, a new-game-only mode where the team with more kills within the time limit wins. As a beta it can be unstable, Mods may not work, and saves may be incompatible until the official build updates.

Beta build. This is an opt-in Steam beta, not the default live version. Enable it via Steam Library → Properties → Betas → “beta”. Beta content changes frequently, Mods may not work, and saves may be incompatible until the official build ships. The current live version is v0.5.0.
