"Fire..."
The commander's voice was deep and full of vitality, but it halted mid-sentence. Zombies that were earlier driven away by the corpse-disrupting agent suddenly started roaring and stomping towards the troops in a frenzy.
The expression on the commander's face changed rapidly, leaving him confused.
What was going on?
He was flustered, but his soldiers reacted quickly. Within a few seconds, they formed up into square arrays, launching attacks on the zombies converging from all directions. Bullets and lasers flew about wildly.
"Damn it!"
The commander's expression changed again. Firing guns now was not the wisest move. The gunfire would attract even more zombies. Their current situation was not like when they first entered the city. Now, they were surrounded by zombies.
