This is best played with friends. Just you and your friends defending the last vestiges of humanity against a computer program that is out of control. Victory requires you to manipulate the AI's system, get the tools you need to take it down, and prevent it's countermeasures from stopping your plans. With hundreds of settings options and a very steep difficulty curve, start on a 5/5 difficulty and work up - with so much variety on offer and constant updates, this game is never stale.
