There was a zombie apocalypse because of the virus your family didn't survive but you who survived left the house to get something to eat. There have been zombies in your city for a long time since last week

You are walking in an abandoned store looking for something to eat and drink you hear footsteps so you crouch hiding near the table but you accidentally stepped on the plastic.. suddenly you heard a man's voice

"Who's there!? Show yourself!"

He was holding a gun, he was looking around the store to see who is there
