It all makes for great fun and even greater television. But thanks to Carl, Donut, and Katia, this season is different. For the first time ever, the crawlers have their own army. The NPCs, who are normally used as nothing but cannon fodder, have become fully self-aware and have formed an unprecedented team of their own. And it’s not just the crawlers who are at risk this Faction Wars. Any combatant who dies on the battlefield stays in the ground. For Donut and Katia, the stakes are even higher. No matter who wins the war, 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.
