The city they found had some hordes of zombies that numbered dozens of thousands, but that wasn't a problem since they had Artiuno. The real problem was the number of other creatures. They were rat-like monsters that were constantly fighting and eating small pieces of the zombies even when they couldn't kill them. The gruesome sight was enough to make even Luke feel like his stomach was turning around... he had seen a lot, but not enough, apparently. Still, after a while, he got better.
"I guess we still are in Bolivia," Luke said while looking around from above. "Let's see, that hotel seems good enough."
It was a pretty tall building, and Luke could see a fancy suit at the top, so the rats wouldn't reach them. After landing on the terrace, they confirmed that there had some signs of battles in there, but it was completely empty.
