Quick summary

40k for OpenXcom is a total-conversion mod that places OpenXcom gameplay inside the Warhammer 40,000 setting. You lead the Imperium’s forces as the planet’s Force Commander, managing a beleaguered world while facing the forces of Chaos. The conversion adds new unit types, bespoke gameplay systems, and a story that draws heavily from Warhammer lore to change the base game into a grimdark tactical experience.

Installation steps

To get the mod running, follow these steps:

  • Ensure you have OpenXcom Extended (OXCE) installed and working.
  • Download the mod archive, then extract its contents into OpenXcom’s "mods" directory.
  • Start OXCE, enable the 40k mod from the mods menu, and launch a new campaign.

Customization options

Players can tweak presentation and audio to suit their preferences. Notable optional additions include:

  • Visual customization for Space Marine chapters (paints, insignia, and armor variants).
  • Adjustable music and sound settings to switch between atmospheric tracks or silence.

Updates and reliability

The project receives routine updates and bug fixes, which helps preserve ongoing campaigns and keeps compatibility current with OXCE. Regular maintenance reduces the risk of major interruptions and improves stability across releases.

Who will enjoy this mod

This conversion is best suited for players who appreciate tactical squad-based gameplay and are fans of the Warhammer 40k universe. It’s an attractive pick for those who want a themed OpenXcom campaign with fresh units, mechanics, and a dark narrative.

Alternative suggestion

If you’re exploring different experiences outside of this conversion, a popular alternative recommendation is Oblivion Remastered (free). It offers a very different fantasy-style overhaul for players seeking another dramatic change of setting and mechanics.
