SteamAbout TDoom

The aliens won. The Ark hasn't launched yet.
The year is 2094. The Kthar dropped biocapsules on every continent and Earth's armies collapsed in 72 hours. All that's left is the Ark Protocol: evacuation rockets packed with civilians, stranded in besieged cities, waiting for their engines to warm up. You are the tactical AI commanding what remains of the armed forces. Build the defense around the Ark and hold the perimeter until liftoff. Every point of damage to the Ark is people who never leave the planet.
Deploy. Hit start. Watch.
Every decision happens before the battle. Place and rotate each unit: a tank's facing sets its firing arc, a fighter's heading sets its bombing run, and a helicopter patrols the area where you put it. Then watch the horde arrive by the thousands, and then by the hundreds of thousands. You will lose. And every defeat pays. The credits from each attempt buy upgrades in a permanent skill tree. Next time, you come back stronger.
