My breath was coming out in pants, my lungs burning as I continued to run to my second bunker.
The tunnel was dark, and I didn't bother to grab a flashlight when I ran. Luckily for me, it was also a straight line from the first bunker to the second, so I didn't really need to see.
That was when I ran face-first into the wall in front of me.
My momentum caused me to fall back on my ass, my chest hurting like a son of a bitch, but I needed to get up. I needed to get to safety.
Coming to my feet, my legs like jelly, I stuck my arms out, trying to find the door in front of me.
I felt the cold metal of the door and slid my hands around as I tried to find the hatch wheel in the darkness.
Finding it, I quickly started to spin in.
The door let out a soft groan in protest as I pulled it open, and I prayed that the zombies couldn't hear it.
