When the android underground rang the alarm, the museum's entrance and exits were blocked by metal gates that descended from the doors' frames.
The trio on the surface were startled, scanning their surroundings with haste as the alarm deafened them from their communication with the group underground.
From the wall, a large, secret compartment opened up, releasing a human-looking android with the features of a woman who stepped out into the main hall with confidence, scanning her surroundings.
"Facial recognition failed—Intruder suppression, commencing," said the android, prompting Zac and his group to scatter.
As the android pointed her palm forward, her forearm extruded a gun barrel from it, releasing a barrage of projectiles that made the trio get into hiding behind the art pieces.
