An overwhelming urge to leave this city as fast as you can overtakes you. You drop back down the hole and race out of the building. Your hope is to make it back to the gate you came in. It being on the far side of the city, you hope that there will be fewer lizards that way, and that you can escape back outside.
At the entrance of the hospital you find that most of the guards have fallen to the onslaught of the lizards. You grab a spear from a dead man and charge forward, trying to force a path clear.
The lizards fall back for a few moments, but quickly regroup and surround you. You continue stabbing at the ones blocking your path, but now find yourself constantly spinning around to keep off the ones behind you.
The going is slow. For every one you are able to maim or kill, two more appear in its place. For every step you gain ground at one moment, you seem to lose two more the next. One lizard slashes at you with its claws that connects just enough for it to hurt. The situation is bad, you're getting tired, and starting to make mistakes, and they outnumber you.
After what seems like an eternity, you spot the gate about 200 yards away, but too many lizards still block your path for you to make a run for it. While trying to figure out what to do, another, much louder and more violent explosion rocks the chamber, knocking you off your feet. The lizards scatter away as large pieces of the ceiling begin to break loose and fall around you. A cave in!
You jump to your feet and run as hard as you can, but the gates have collapsed, blocking that way out. More rocks fall around you as you look around for another way out. A horrible sound above you causes you to look up. You can't see anything at first, just a darkness spreading over you, then realize that is the entire ceiling is dropping on top of you as a single piece.
Mercifully, you don't feel anything when it hits.
The End.
