So there's this huge building on the moon, except it's on a water ocean. Inside the structure, me and another person (a girl?) are fighting a kind of shapeshifting monster that likes taking the form of people. Nor Pennywise for a change, yay! I think I shot him with a sniper rifle when it was about to shoot the girl. In the end, the massive building (and I mean massive) exploded. The view cut to a control room back on Earth, where multiple Men in Black watched the building explode. An alarm blared, and a level 6 emergency was declared on the moon. Then it cut back to the building, which simply vanished. I saw the building wasn't really 'in' the ocean, but rather hovered over it using giant drone-like propellers. As the building vanished, the propellers stopped working and plunged into the ocean. We were swimming now, and reached a tropical island. We found some friendly natives, who helped us. Then some other weird stuff happened, like the chief was wearing a nose like a clown nose, but made from a hollowed-out nut. The chief then vanished as well, leaving us with his stuff.
