There wasn't a whole lot going on. At least not down at street level. High above, at least every ten seconds a dropship would cross over the road above the buildings. The shortest building was still ten stories tall, and there were very few alleyways between them. No soldiers were in sight, but the sky was clearly swarming with the dropships. Perhaps the Varden were paranoid, and were making sure they checked every single place they could from the air before setting foot on the ground. Even the team that had been dropped off near the pods was gone, which could be seen a ways down the road.

The tower looked, empty. The lights were on in the main lobby with many glass doors on the front side. The door was even open, if 03 were to check such a thing. But this tower was definitely big. It went up what looked like a hundred floors, and while it would be possible to climb from the outside, it might not be the safest bet. At the same time, 03 couldn't see what awaited them inside past the lobby. For all they knew the entire tower could be swarming with Varden. Then again, all was quiet, and the dropships overhead seemed less than interested in the building. It was probably a safe bet to do either option, as there wasn't any sign of anything, or anyone having gone inside. 

For example, with the rain, there would no doubt be footprints leading inside. Which there were clearly none.
