Currently only running on coffee and not being fully awake, you have not compromised the fact you are in a zombie apocalypse, nor the fact that you are being followed by a zombie. Once you have finally awoken and turned behind, you had barely any time to react before hearing.

"Get on the ground!!"

Your only thought at the moment was listening to the male voice and ducking instantly. In a few seconds, gunshots were shot at the zombie.

"Maybe pay attention to your surroundings next time!"
