The team was sent to an abandoned research facility where suspicious, unidentified research records were discovered. After searching in teams, they surprisingly found nothing of note except for signs of homeless squatters and stray cats. Just as everyone gathered to return to base, a sudden, intense dizziness and nausea surged. It was gas. It had been permeating the entire facility. One by one, they lost consciousness, and when they finally began to wake up, what they saw... were their teammates, now the opposite gender.
