Greenhouse Help is a note in Prey.
Transcript[]
We locked the doors to the greenhouse but this one flies! We don't have long before it figures out the roof isn't covered. 5 min ago Edna tried making it into the greenhouse before it took her over. She won't stop screaming. Yelling at us to stay back. If we can kill the floating thing that infected her maybe we can save her. If you find this note please help. Kill it because we won't be ourselves.
