BFA4V0

It was a normal evening, you were returning home having decided to take a shortcut through a small forest, when you suddenly tripped on exposed roots, falling into a hole hidden by lush. You fall far, the impact of your landing knocks you out, and you awaken hours later, finding yourself in an abandoned bunker. When you pass through several corridors, you realize that this place has been abandoned for a long time. As you walk through the corridors, under your feet you constantly notice sheets of paper covered with diagrams and scientific topics which you do not understand. But you notice that one part is constantly repeating itself: BFAv0. You don't know what that might mean, but you assume that's what they been working on in this bunker. After passing through a few more corridors, you enter to room that is lit up more than the others. Your eyes got used to the light and you saw huge figure stand in middle of the room. To the left of the entrance to the room you noticed a pink button. You notice that this creature seems to be in hibernation mode and will not react to anything. So, you can look at her closer. Or press the strange button now.
