Okay, I've found something really interesting. I found a way into New City from Shadow's Castle Town, by glitching through the right corner of the wall, not just the door, and jumping into the load point. I did this just after M15. What I found was...odd. Cars everywhere, almost everyone said the same line, and a bunch of mirrors for different places (IDK why). But the most interesting thing was it loaded a mission when I walked up to the area near the mirrors. The text during the loading screen was blank, but it seemed like a new mission. It starts off by saying: "Destroy all the enemies and protect Company Employees!" and some enemies appear. The mission has a lot of them. After them, a person named "Mazzola" says: "We at Rimlight secretly obtained information about the Solaris Project that Duke Soleanna was working on, and learned about Light Cores. Once the Rimlight President learned the secret behind the Light Cores, he told us to collect them, to make a fortune from the energy. As you know, Light Cores are very dangerous. Some of us didn't want to do it, but I couldn't stand up to the president. And then... this happened. But, I was wrong. I need to do what's right, instead of trying to make a profit. Mephiles? No, we've never heard of him before." The mission doesn't have a result screen until you talk to him a second time, and he says: "But, there was a large Light Core reaction in the desert area a short time ago. Maybe that has something to do with it." There is no save after this results screen, and you are brought back to the door you came from. There are other missions that are normally in New City, but at the wrong places or with duplicates. I was able to go to the Flame Core and Crisis City mirrors, but they took me nowhere. Same with the Radical Train one somewhere else. I'm not sure if this is new or not, but it is interesting. If anyone has done this before, please say so.
