The ninth floor. Nine armies, each led by rich and powerful aliens from across the galaxy. Each team has one objective: to capture and hold the castle at the very centre of the battlefield. Strategy, alliances, pitched battles, and, of course, betrayal...

It all makes for great fun and even greater television. After all, none of these powerful aliens really die when they're playing war. Except this time. This time, winner takes all. Those who fall, stay in the ground. As the AI continues its rapid decline, Carl and company take advantage of the chaos. For the first time ever, the crawlers are fighting back. They are now one of the nine teams.

And this season, there's a tenth army on the playing field. The NPCs, who are normally used as nothing but cannon fodder, have become fully self-aware and formed a team of their own. For Donut and Katia, the stakes are even higher. Only one of them will be allowed to leave this level. If they all want to survive, they're going to need a little help from a veteran or two.

This is it. This is what they've been fighting toward. This is war.
