So I went to the core to check out that image that people have been talking about and when I went to the core, I noticed that some of those weird vent things around Rasputin's core were lit up. In total, the vents that go up the walls (excluding the ones on the side when you enter the core) total 40, with 13 lit up. Could this be significant? I will upload a screenshot later when it uploads to the Xbox Cloud
