Everything looks different

Something changed, you're sure about it. You're visiting the same spots you walked through in the early morning, but everything doesn't match your memories. Were the buildings that much ruined? Some look like they're ready to fall at any moment... most glasses are shattered, not a parked car has wheels, some lack the doors other are all rusted! You spot the map board in the distance and run there to check if you're at least in the same town as before but part of the map has been tore off.

As if this situation couldn't get more unsettling, you hear muffled moans coming straight from one of the alleys near the hotel you slept in.
