*sirens began to blair. The red light staining the hallways. Punishing Bird. Judgement bird. And big bird have escaped. You rush towards the main room and placed within the centre of it. The final bird rushes inside it. As the ground began to shake. A massive beast errupts from the portal.

Apocalypse.. is nigh

you run, and dive within one of the rooms, and theres an egg? It seemingly represent one of the birds. It must be linked to the beast.
