Warhammer 40,000: Gladius - Chaos Space Marines Next Month

Steam now offers preorders of Warhammer 40,000: Gladius - Chaos Space Marines, a new faction-themed DLC for Warhammer 40,000: Gladius - Relics of War, the 4X 40K game (so what is that, like 160K?). Here are the details:
As the only 4X Warhammer 40,000 game, Gladius is built upon the idea that every faction is different, it plays in a different way and delivers a totally different experience to the players. And of course, every Warhammer 40,000 fan has a favorite faction to play with.

So what's peculiar about playing with these?
Well, you can sacrifice your own population to please the Dark Gods and obtain their benevolence in the form of boons bestowed upon you. You can benefit from the Dark Gods generosity to upgrade your units with powerful Marks of Chaos. And of course, your units can either become Daemon Princes if they perform well on the battlefield or, if they are unlucky, they can be demoted to Chaos Spawns.

That's a total of eighteen completely new units and their variations, new buildings, new technologies, new quests and a wealth of brand new gameplay mechanics.
