The Infinite Museion DLC

Warhammer 40,000: Rogue Trader - The Infinite Museion is the third story expansion for the base RPG. It adds a new companion, a Tech-Priest Manipulus with a shadowed past, and introduces artefact hunts inside Trazyn the Infinite's vault. The Steam code delivers the content directly to your library on PC.

For Rogue Trader owners wanting more story

This DLC suits players who have finished the main campaign and want fresh narrative threads, a new party member, and additional vault exploration. It does not suit anyone who does not already own Warhammer 40,000: Rogue Trader, because the expansion requires the base game to run. Buyers seeking a standalone experience should look elsewhere.

Steam DRM requirement

The product is a digital code that activates on Steam, so a Steam account and the Steam client are mandatory to download and play. There is no physical disc and no alternative DRM-free version. If you cannot or will not use Steam, this code will not work for you.
