Squaring your shoulders, you decide to troop down the stairs, checking the doors on each floor to see if any are unlocked.

Thirty minutes later, your top is soaked through with sweat, your knees hurt, and you’ve reached the first-floor stairwell with no luck opening any doors along the way. Taking a deep breath, you try the door to the lobby, but it’s locked as well.

There’s still one more flight of stairs down to the basement, however, and, resigned, you walk down to the door below. You pull the handle, and, to your immense relief, it opens! You walk through the door and into a dank hallway that’s dark on either end. A light flickers overhead before winking out, surrounding you in darkness.

Unnerved, you turn back around, intending to return to the first-floor stairwell, but the door must have locked behind you.

You're trapped.

Suddenly, you hear a muffled scraping sound followed by a deep moan.

Your mouth dries as your heart pounds.

“Hello?” you croak.

The scraping and scuffling get closer, and you can just make out a low voice moaning, “Brains.”

Before you can react, shadowy figures appear out of the darkness, and as they get closer, you recognize them for what they are. Zombies.

Screaming, you turn around and start running.
