It was only me and my partner as we went towards the nearest. Quickly jumping over the platform, we made our way inside while shooting the zombies inside. The zombies outside couldn't come in cause the platform was too tall for them to simply jump over it.
Going to the back, we noticed there were only two windows as we made our way towards them while still being on guard. Slowly walking towards the farthest window, I opened it not making much noise, and looked down to see the same small alleyway I walked in. I turned to the sides and finally caught the ladder.
It was within an arm's reach from me to the left side. I looked to the right and saw my partner's joyous expression. Giving him a nod, I took out the walkie-talkie they gave us before.

"We found it. Once again, we found it. It's in the food court section in the sound shop."
