We have just come to realize that we have been ambushed. Clearing the first and the second floor has found us peace that they are not hidden behind any of the walls or, as some of the daring ones will do, in a nearby closet. These buildings, even this one, which is a bit more modern, they all have their own creek and cracking sounds. If some asshole on the very far side of the third floor opens a door, we are for sure certain to know about it.
So we are making the way upstairs slow and steady. Make one wrong move, and it just might be the end of you. It is you or the man on the other side of the gun; no time for hesitation. If you want to make it alive out of this building today, you should be alert, and you should not falter.
