Exterminatus : Destruction of all life on a world by the Imperium of man.

This mod is set in Games Workshop's, great Warhammer 40,000 ( 40k ) universe, as seen in Dawn of War and our previous mod WH40K : Rival Species.

The 40k universe is set in the year 40,000 by which time mankind has colonized millions of worlds thought the galaxy by interstellar warp travel. Humanity is ruled by a vast, uncaring, priesthood/bureaucracy on Earth in the name of an all powerful God/Emperor. A galaxy of insidious alien races have threatened and fought the Imperium since its earliest days in innumerable wars and battles.

Developers of this mod have deliberately chosen to include only the Imperium and Tyranid races out of the many that exist in the 40k universe in order to focus on the quality and polished that the mod would not have otherwise. Please do not ask about the other 40k races.

Exterminatus is feature complete and the game is fully playable. A public Beta is available for anyone that wants to try it. New Beta versions will be announced here, but there are also fortnightly public Alpha builds which being incomplete, unbalanced and often unstable aren't really worthy of news on ModDB, but are detailed at 40ksource.com.

Each map sees teams of Marine and Tyranid players competing in a series of mission objectives, culminating in a battle to decide the fate of the planet. This mod is purely multi-player, there is no co-op mode or player bots available.

Players that do well for their team are rewarded with the option to use more powerful player classes including special and heavy weapons marines, terminators, the tank like Carnifex and terrifying Lictor.


  • Two teams, with their own distinct appearance and game play styles
  • Three tiers of player classes, achieve success to unlock superior classes
  • Twelve playable classes, each with their own unique sounds, weapons and abilities
  • Mission and Objective based game play, with progressive spawn waves

Getting Together
Regular scheduled games are being hosted on a number of dedicated servers several times each week usually mid-week and weekends at between 7 and 8PM GMT. Please check our steam community page for upcoming scheduled games and servers addresses.

6 comments by ChromeAngel on Jan 9th, 2015

Since July of 2014 DontAsk4470 has been contributing new and improved features to Exterminatus to introduce a new hivefleet and new shaders compatible with Source Film Maker. Beta 8.10 is the culmination of this effort, with both races re-branded as Hivefleet Leviathan and the Blood Ravens Chapter of space marines.

Work is in progress to update the other chapter skin packs to use the new marine skin features and cope with the change to the default chapter.

If you are one of our 1800+ watchers you may have been caught out by the mod's change of image. To go with the mod's new look I'm switching to out classic logo, the Source "tag" around the classic GW Tyranid logo.

I would ask if you would like to submit this to be greenlit, but it might interfere with copyright issues, due to it being "Warhammer 40k" and all.

Decent mod, but an unhelpful community who only open their mouths to troll and talk shit like it's a competitive shooter. Makes MOBAs and Youtube comment sections look civil. Avoid. I simply asked how to get ammo for the Termies stormbolter and was told "to quit acting like it's CoD", whatever that was supposed to mean. I proceeded to ask again whether I was supposed to just let myself die or if there was an ammo point or something, and didn't get an answer. Then a match later, as I was lost on…
