Allan's father was fighting the creatures in front of the shelter, with him and at least a hundred police officers behind a makeshift barricade made of cars. The police officers were using their brain crystal powers to kill the beasts, but their numbers were too high.
Allan's father was a skilled fighter, and his presence gave the other officers a sense of security amidst the chaos. However, despite the police officers' efforts, the beasts seemed to be multiplying, and the situation was becoming direr by the minute.
The beasts that came in were not very strong; at best, they were on the low end of the spectrum, so they were not immune to bullets and laser rifles. But their sheer numbers made it difficult for the police officers to contain them. Allan's father wanted to call for backup, but there weren't enough people inside the city so they could do nothing.
