The problem was trust!

Probably, everyone was suspicious of the spaceship.

After all, who, in their right mind, wouldn't be?

Although three hundred people had appeared on the spaceship today, this number was insignificant compared to the city's population.

Assuming that only a quarter of the city's population survived, that would still be a million people!

Out of a million survivors, only three hundred had the courage to face the zombies?

The answer was clearly no!

Think about the survivors' position: 

A mysterious spaceship appeared in the sky, and without knowing its origin, it claimed to offer a safe shelter if you killed three zombies and handed over the glowing stones in their brains.

This wasn't a good way to gain trust!

"I need to think of a way to gain trust quickly!"

"Otherwise, with each day of fewer survivors, I'll have fewer energy cores and, most importantly, fewer survival points."
