Underground Subway.

The next day, Rex was already stationed by the subway entrance, scanning the dimly lit surroundings where the Aegis Sentinel squad had been wiped out the night before.

Several other squads were positioned around nearby subway entrances, ready to intercept in case the Void Crawler emerged.

Just in case, the hulking Mauler Juggernaut was on standby too, its massive frame looming nearby, ready to respond if any other giant infected decided to make trouble while they were down below.

Rex tapped his foot impatiently. "Cleo! We're waiting on you! Come on, I can't wait to get down there and have my ass handed to me!" He called out, grinning, though he was only half-joking. Cleo had kept him waiting nearly an hour while finalizing updates to the assembly factory construction.
