I THINK THE WORD WE'RE LOOKING FOR IS "APOCALYPSE" (Ghostbusters fanfic)

"THE INJURY"

As we were walking back to camp, we encountered an army of zombies (there had to be at least one hundred of them) and what was worse, these zombies had weapons so they could fight back. I hate bragging but I killed a bunch of zombies, we were fighting this zombie army for at least two hours. Finally we defeated the crowd of zombies, but as soon as we tried to leave the site a zombie snuck up in front of us and set off a familiar looking bomb...it was the "ecto bombs" I made for the team. The explosion was large but luckily none of us were killed except for the zombie. At first I thought we didn't suffer any injuries until I looked over at Erin, she had a broken piece of glass stuck in her right eye socket. Erin knew something was off when she couldn't see through her right eye and she felt a tremendous pain in that same area, so she felt her right eye and felt the glass in it and then she started freaking out. I tried calming her down while Abby was taking the glass shard out of her eye. But once we took the glass out of her eye socket the eye came with the glass, Erin had no right eye now and freaked out even more and even passed out at one point. Luckily we got some disinfectant so the wound wouldn't get infected and an eyepatch so she wouldn't have to look at her empty right eye socket when ever she looks in the mirror. I still had that one question that has been bothering me: where did that zombie find our equipment and how did it know how to use the equipment?
