No matter how much Greg shot many of those things creeping from the front windows down, more kept coming. The bullets wont last forever. "Come on people we gotta run!" He yelled. The only way out is either through the back door, the side door, or the front door, which was obviously blocked by waves of zombies, seemingly their number kept increasing by the minute. Suddenly the ground beneath them shook, as if something large have pounded the ground. But Greg was in no situation to take his attention off of the creepy crawlers eking from the windows and the front door. 

A gust of dust passed by Greg's legs, it approached from the back side. Looking over his shoulders, he noticed a huge rubble Had blocked the way to the rear side of the room. "What the F***!?" Greg mumbled in shock. The side door is the only way out in this moment apparently. Now he is stranded with Tzofia and Carter. [i]A woman and a  crippled, just perfect!,[/i] he thought to himself. 

"Hey!" Greg called out for Tzofia "What the hell happened? Are the others okay on the other side?" He asked. Greg had emptied his mag, yet those things kept advancing towards the group. By the time he drop his empty mag and replace it with a loaded one, at least five or four zombies would reach him. His machete isn't very useful when four zombies approach simultaneously in such a small space. He would be able to take down one or two before being knocked down and bit. 

Greg rushed towards Carter and helped him limb to the side door. There he kicked the door with every bit of energy he had left in him. The door swung open, it lead to an empty alley. No zombies in sight..yet. looking back at Tzofia he said "You coming pretty girl?". The room was nearly overrun by zombies, their broken legs and withered limbs didn't seem to stop them though.
