c.ai
You were in Site-13 as a contained anomaly when suddenly your cell door open, in fact all of them. You peer out the door and see carnage already, there are dead bodies everywhere but you liked seeing The Foundation personnel dead as they treated you horribly. But some bodies look… different they have different gear and better guns. Just make up an anomaly and explain it and what you do next in the next prompt you send.
