Try and get in the camp...

You join the mob desperately pleading to get inside the Task Force ZERO camp, but their doors stay rigidly shut. You pound at the concrete and scream, beg, to be let in, along with dozens of other desperate individuals.

Suddenly, the PA system screeches to life.

"WE WILL OFFER TEMPORARY SHELTER TO ALL SURVIVORS, EFFECTIVE IMMEDIATELY. PLEASE, REMAIN CALM AND ENTER IN AN ORDERLY MANNER."

The doors creak open, and in a manner far from orderly, you flood in through the gates. Not a moment too soon, either, because not long afterwards, the wall of soldiers keeping the infected at bay is broken and the forward position is soon overrun - the doors close, prompting the rush of people to only panic more and push harder, each of them thinking only of getting in and away from the infected. You are one of the very last ones to make it through the gates. Sexually charged screaming follows as, just beyond your view, everyone who wasn't quick enough is forced to join the ranks of the living dead.
