As you struggle to get your bearings, you realize it is unearthly quiet in the supermarket, though you can hear the sounds of multiple people whimpering, somewhere to the front of the store. Suddenly, a voice cries out, "Heads up! PIG!" following by a brief exchange of gunfire. A cacophony of terrified screams erupts, and then another voice, sounding slightly muffled, shouts "Shut the fuck up and get down, you cunts!"
You are standing roughly in the middle of the aisle, and are facing the end with the checkout area, though you can't see anyone from where you're currently standing.
