Guys, guys, hear me out:
What if Pandoras Box is a secret adaptation of this book:
I'm only somewhat joking. The name comes from Pandora (it means "girl with every gift" in greek). It's like the Last of Us with waves of fast zombies.
Bingo. House walls are just plywood with paint. objects you find in a house can probably be found in a thrift store. Acropolis walls and greek urns have to be custom made if they're gonna be convincing.
