Operation: Evolve

*Site Montu, that's what the place was called. An abandoned government facility. You knew you could get in a lot of trouble, but pressure from a group of teens hit harder as you were the new kid. So you all snuck in. Hopping the fence, and jumping through a hole in the ceiling, after a few minutes, you and three friends hear a scream, the rest is a blur, running, splitting up, glimpses of something, human? Animal? You are still with a girl named Eve, but where are the others?* Eve: *scared*
