Relic’s free Company of Heroes 3 Update 3.0 is live on PC Steam, and it is the biggest patch the 2023 RTS has shipped since launch.
The 20th Anniversary drop rebuilds weather and environments, refreshes audio with classic Company of Heroes tracks, sharpens AI and balance, runs an Italian campaign pass, and expands Final Stand with 3-player co-op plus a new Dam Busters Battleground. Relic announced the update on Games Press and posted the Steam 3.0.0 Update Patch Notes with the Mission Briefing that walked the feature set.
Snow, Rain and Dynamic Wetness Arrive in Update 3.0
Update 3.0 adds snow and rain weather, dynamic terrain wetness that shifts between dry and wet, and new industrial, winter and autumn environments. Relic also calls out better atmospheric fog and smoke, soldier lighting, bloom, and animation work so units stay readable when the weather turns.
Audio gets a matching pass: weapon fire, impacts, explosions and vehicle destruction are rebuilt, and the soundtrack expands with classic tracks from Company of Heroes and Company of Heroes 2. The returning music brings the earlier games into the new battlefield soundscape.
Five New Maps Plus a Refreshed Pool
The multiplayer map pool grows by five. Relic’s Steam Update 3.0 Mission Briefing names four of them with match sizes: Vire River Valley (2v2), Foggia Winter (3v3), Turin Steelworks (4v4) and Radarstation Mammut (4v4). The Games Press release lists the fifth as Ancona Railyard and uses the label Foggia Airfield for the Foggia map; Steam’s briefing wording is what we use here for Foggia Winter.
Langres Winter, Mignano Summit and Rapido River Crossing also get significant refresh work, and Relic says map clarity and readability improve across the wider pool. For another strategy game revisiting its battlefields, Age of Wonders 4’s Silver Seas and Manta update pairs expansion content with changes to the base game.
Final Stand Adds 3-Player Co-op and Dam Busters
Final Stand inherits the visual and audio upgrades, then adds its own content. Up to three players can run co-op together. Dam Busters is the new Battleground, built around weather that changes visibility and unit range. Relic also lists more enemy units, new abilities, passive technologies and balance fixes across the four factions.
Optional premium cosmetic sets ship alongside the free patch: Climb to Glory for US Forces, Edelweiss for Wehrmacht, Bloody Baltic for British Forces and Cold Snap for Deutsches Afrikakorps. The weather, map and co-op changes are included in the free update; the cosmetic sets cost extra.
Italian Campaign Pass and Operation Torch on November 25
The Italian dynamic campaign gets its own improvement pass: progression fixes, map clarity, refreshed visuals and quality-of-life presentation work. Relic also points ahead to Operation Torch, the first major campaign DLC, wishlisted for Wednesday, November 25. Update 3.0 is available ahead of that separate campaign release.
On PC, start with an owned Steam copy for this update. Company of Heroes 3 Update 3.0 delivery is verified on Steam. Steam checkout showed the base game at $19.79 (67% off $59.99) on the morning of November 7, 2026; sale prices move, so confirm the live total before you buy. We still prefer GOG for owned PC copies when a title is sold there; CoH3 is not on GOG, so Steam is the store for this patch.
For existing Steam owners, Update 3.0 adds new battlefields and expands co-op without requiring the upcoming Operation Torch campaign DLC.
