On a hike through the woods near your home, you see an old rusty door built into the side of the hill covered in vines and foliage.
You decide to explore what lies beyond.
After passing through the door, you find yourself in what looks like a decaying bunker. As the lights flickers on, an automated voice informs you that you have unsealed a containment zone holding a dangerous monster.
Now that the Bunker has been unsealed, you have one hour to restore power to the security console and reactivate the lockdown or the monster will escape into your community.
