Leon and Ashley saw the blue gas begin to flood into the hallway and covered their mouths. Leon took Ashely's hand and led her further up floors to one of the unlocked safe rooms. The first lone zombie was a man in a suit for the party. They were able to avoid him and run around. Soon, debris was blocking their path and the had to work together to move it. Two more zombies came out of nowhere.
Ashley had dove forward to dodge and landed near a fallen security guard, his gun still tight in his hands.
Meanwhile Leon began to fight with his bare hands, trying to move the other zombie out of the way so he could draw his gun and reach Ashley.
Leon rushed to help her up, when the second zombie had recovered and dove for his neck behind him. Leon had only time to turn around and see the putrid zombie's rotting flesh over its face...
...followed by a flash and a splat as a large gusher of blood spewed out of the undead abomination's head.
He turned to see Ashley standing there panting...with a smoking gun in her hand.
"Leon!" Ashley yelled and pointed her new firearm behind him.
Leon was fast enough to dart out of the way of the first zombie, and this time he was able to draw his gun before the zombie reached him. Bang!
The zombie was forced back from the gun's impact as the other monster rose to its feet beside it.
Leon and Ashley stood their ground and prepared...
"Now! Fire!"
As if they were doing this for ages as pros all their life, the two survivors pulled their triggers, and the brains of the remaining fallen men splattered over the walls as the remnants of their bodies dropped to the floor.
They ran up a flight of stairs to discover more secret secret service men that were still alive and had stayed behind valiantly to hold the enemy off as the Leon and Ashley, the last and only two survivors, made their way to safety.
At this next flight of stairs, zombies and rubble had begun to fall down. Stepping over corpses and dodging falling debris, they jumped as the wooden stairs gave away from out beneath their feet and pulled themselves up to the final floor.
Finally they had reached the metal panic room and pressed the button... only for steam from the air purification system to slowly come forth from the floor as the door raised ever too slowly.
The safe room took a long time to open, and so in an empty long corridor the two survivors held off the onslaught The other agents eventually perished
The first door of the decontamination chamber was now opened and they faced a second door. As they ran in and slammed the button to close the door, many figures could be seen running inhumanly towards them. Leon and Ashley by now had emptied their clips and waited for the end...
Finally, the door closed, and the undead banging on the door began. After a human scream outside it however, the attacks seemed to cease and footsteps could be heard moving away.
...for now.
