During their first stay, the aliens spend most of their time inside their dome, and we humans were still researching all sorts of stuff, including how to get through the dome. This time it was different: we knew how to get through the dome routinely, and the aliens spent a lot more time exploring outside the dome.
The result was a lot more conflict, and the first confirmed alien casualty. A sniper dinged an alien wandering above ground, and that must have damaged some sensors because as it headed for cover it ran over a mine, which slowed it down. Then it made a left were it should have made a right and got lost above ground. We damaged it some more to where it was down to the speed of a car and moving in circles in a park, and then we pounded it with heavy artillery. The pieces were at the bottom of a twenty foot deep crater when they finally stopped moving. We got a few pieces out before the alien rescue team showed up and took the rest back. I won't say much about those who died there, except that they were heroes who gave their lives for a really good cause. Those few chunks of alien we got out of that pit were invaluable. Over the years they have told us a lot about those aliens and Korex Armor was developed from those pieces.
The fighting over that second month was a lot nastier than it had been the first month, and a lot scarier. The aliens where aggressively hunting people down and scalping them. They launched raiding parties into the surrounding urban areas, and they were sneaky about doing it. They would find hospitals and relocation centers. They would show up at public events. They were definitely attracted to large gatherings of people, and the media was having a field day with the vistas of scalped bodies they would leave behind.
We humans, on the other hand, were working hard at defensive tactics. Guns worked, if you could sneak up on an alien and catch it standing still, but that was like belling a cat. We tried doing some decoy events, but the aliens would spot the surrounding hardware and either blow that away first, or just not show up.
There was a lot of talk about using nukes... a lot. But the situation never seemed quite right for them. First off, nuking the city centers would destroy them even more than the aliens had. And second, none of the nukes used in the space battles had proved particularly effective -- the aliens were just too fast. Still, as the hawks recovered their standing, they called for nukes.
There was a curious interlude going on at this time, too. New Zealand picked up some of the relocation camps, and one of those was located on Stewart Island, at the extreme south of New Zealand. A village was established on the edge of the temperate rainforest there, on the lands of an abandoned sheep farm, and the farm was reactivated.
Just before the aliens left, it was reported that an alien was on Stewart Island. In the excitement of aliens leaving, it was nearly forgotten and then dismissed as a wild rumor. But when the aliens came back, the people at the village reported the alien was back. They also reported that he didn't bother people. He was interested. He watched people, but he didn't scalp them, and he ran away if they threatened or hunted him, and then came back.
It only took a week, or so, for people of the village to accept that "their" alien was different, and to stop hunting it, or running from it. They had a meeting, and then started working hard to keep alien hunters out of the area. A week after that, the alien started to wear a different outer covering. The covering made the alien much larger and when he was in it, he sort of lumbered along in a way that looked he was being a human puppet on strings. It took a couple days for the villagers to figure out what was up, but someone finally hit upon the idea: "He's disguising himself as a human!" It gave everyone in the village a big laugh, but once they figured that out, they new how to treat him. They treated him like a human.
The videos of this are hilarious to this day. The alien would lumber through town with it's misshapen body and puppet-like walk, and the people of the village would say, "Good day." to it and go on about their business.
But one really important discovery came from this odd interlude: a couple of enterprising villagers tried to barter a sheep with the alien, and the alien did barter back!
Sheep... Hair!! Those goddamn aliens were scalping people for their hair!!!
As soon as we figured this out, the barbershops were open twenty four/seven for the next week, and the alien scalping parties quickly disappeared.
But the aliens seemed to get angry at this. Instead of doing whatever they were doing near their domes, they started searching further and further, visiting smaller and smaller cities. There was a huge panic around Earth. What had been a spectator sport -- watching the aliens trash, Mexico City, Tokyo and New York City -- now became a participator sport for places such as Los Angeles, Jakarta and Moscow. Then the aliens hit Melbourne and Sydney and the raiding quickly ended. Near Melbourne and Sydney the aliens found sheep. That, apparently, was what they were looking for as they went from city to city.
While they were collecting sheep, the call for using a nuke went sky high. These sheep-raiding aliens were out of the city, the damage to human infrastructure would be minimal. But they only did that collecting for thirty six hours.
