1. Behind the counter, under the desk, there is a safe (expert level). Inside, there is a lot of ammo and a pistol.
2. Elevator on the first floor. Take the ride to get to the other part of the building.
3. A huge crack in the building. It is crisscrossed with lots of planks and it extends over several floors. Watch out or you fall. At the very bottom, there is a Deathclaw, so if your character is not sufficiently strong, be careful there.
