A new Epic Map Pack is now available as DLC for Ashes of the Singularity, adding new maps and a new scenario to Stardock's real-time strategy game. The pack is available through Steam or Stardock, and here's an overview of its contents:

Wage an Epic War on Sprawling New Maps
Grab your friends - and your enemies - for some matches of epic proportions on these new, large-sized maps! Holding between 4 and 6 players, each map provides exciting opportunities for free-for-all matches, large team matches, and more. The new scenario will leave you fighting for a planet's control against the enemy Substrate in order to hold onto your fortified plateau long enough to seize victory.

NEW SCENARIO: Against All Odds
Intruder, alert! You've hacked your way into the Nexus that controls both Turinium generators on the planet Qoshyk, but the 4 Substrate entities controlling the planet are now aware of your presence. Mac has subverted the nearby Substrate Guardian and the automated constructs swarms are being held in check for now, but how long will that last?
