Stardock Entertainment announced Escalation, the standalone expansion for their real-time strategy game Ashes of the Singularity. In case you don't know what that means, you won't need to purchase Ashes of the Singularity in order to play this expansion (though if you already own the base game you'll get a discount when buying Escalation).

　　According to the developers, both Ashes of the Singularity and its expansion will continue to be updated simultaneously; moreover, any DLC you've purchased for Ashes will work here as well.

　　In the game, the Post Human Coalition is under siege by a new enemy faction (the Substrate) who wishes to completely wipe humanity out of existence. Players will have to deal with this menace as well as renegade humans trying to recapture their own worlds.

　　Here's an overview of the new features and additions:
