Summary

Steam Workshop Launch

Space Marine 2 has officially opened its Steam Workshop, allowing players to create, share, and install mods. This update introduces the infrastructure needed to support a modding community while maintaining the integrity of the base game's progression and public matchmaking.

Modding Mechanics and Restrictions

To ensure a fair environment, playing with mods will automatically disconnect players from public matchmaking. Modded gameplay is restricted to private lobbies, which can be accessed by other players via direct invites or session codes. Additionally, any progression earned while mods are active is stored separately from the official game save. A watermark is now displayed in the top right corner of the screen during any modded session to clearly indicate the game state.

Resources for Creators

Alongside the Workshop launch, official modder's guidelines and legal notices have been published. A comprehensive technical guide is also available to help creators begin developing content for the game.
