# 30 Floors Up Roblox building guide
Bellwether Heights is the whole map. The stairwells fill with zombies, so most progress comes from vents, lift shafts and doors you open with the right tool.

The power cut changes how you move: read what happens in the first four days, then how the vents and shafts replace the stairs, then the floor list to plan trips.
