Making & Sharing Mods
After purchasing Company of Heroes 3, creators will be able to download the Company of Heroes 3 Essence Editor from the Tools section of their Steam library. A full suite of documentation will be available on the web, guiding players through both simple and complex features in the toolset. Launching the Editor will present you with the Mod Wizard, which asks you which mod type you would like to create and sets you up with the files and panels you need to get started. When you are ready to test your creation, you just need to press the Build Mod button and launch the game – your mod can now be selected in a Custom lobby! When you are ready to share your creation, just Publish the mod from within Company of Heroes 3 – the mod will then be available on Steam Workshop for all players to see and download! Pro Tip: Start with an existing scenario when learning the tools. Starting from scratch can be daunting but building from an existing template will help when creating your first mods.
Playing & Managing Mods
To play Company of Heroes 3 mods, players can browse the Steam Workshop to download a compatible mod and then select it in-game as a Skirmish or Custom match host. Players can also simply join a Custom match that has a modded Map, Game Mode, or Tuning Pack (or a combination) selected. They will then automatically subscribe to, download, and play the mod in moments. Any mods that a player subscribed to will automatically download updates that are published by the mod creator. Players can unsubscribe, report, and view mod details from the Mod Manager, available from the Home screen’s Mod tab. Post-launch we plan to continue supporting, refining, and adding capability into the Company of Heroes 3 Essence Editor and in-game mod manager well into the future. We can’t wait to see the cool stuff you create!
