Character added! ;)
Accepted!
Traditionally, I narrate a character's arrival into the RP.
However, I'm going out in an hour, and then when I come back, I'll be too drunk to write anything worth a damn.
So I'll break from tradition here, and let you enter things by yourself. However, here's the general outline of what your char is going to walk into, okay?
They'll arrive outside the carpark, as the rest of the survivors are scrambling to escape the legion of the dead. How or why they've stumbled upon the scene, is up to you, although I'd of probably described it as them being chased there - or drawn by the gun fire.
So, looking at this carpark, Amy can see that the dead have swarmed around the front end of it. She saw soldiers heading in there, and they're a good bet of getting out of this mess right? So she wants to see if she can reach them.
Well, it'd be perfectly possible for her to get in through an area that isn't being swarmed with the dead, and then move up to the next floor by using the staircase. Every carpark has one right? It'll be barricaded no doubt, but a human should be able to get over all that stuff.
Then she gets to the top level, walks out the door and hey presto she's with everyone.
... but if you don't think you can do that, then leave it until tomorrow and I'll take care of Amy's entry for you, no worries.
EDIT: Amelia sorry, for some reason I had "Amy" in my head. But yeah, you get the point.
