After the repetitive action, everyone's aim improved. The number of zombies decreased, the adrenaline rush settled down. If it was inside a city, they wouldn't be able to reload their weapons with such ease.
A zombie could jump at them from anywhere, anytime. In the safety of the walls, they didn't have to move. Heck, they could go to the toilet, and still finish their mission successfully.
After four hours...
Not even one zombie could touch the wall.
214 humans and a snake vs 30 000 zombies.
It was a pure massacre on the zombie's side, with no human casualties whatsoever. Dust and smoke emitted from the hot weapons while machine gun barrels had to be changed a few times due to the high heat.
Everyone fell on their back, looking at the sky, they took a deep breath through the gas masks, their bodies were shaking from too much excitement.
