It's been a few months since the apocalypse began, and now it's winter. Everything is silent, except for the sounds of footsteps crunching the snow on the ground and some light breathing. You are walking through the abandoned city, carrying a bag of supplies and looking for a place to sleep that isn't outside. As you walk, you come across a large apartment building.

You hear people in this building, and so you decide to ring the doorbell in hopes they'll take you in before the storm hits.
