30 Floors Up food, water and barricades guide

How to test the 30 Floors Up supply and defense loop, with a useful barricade comparison instead of an unsupported permanent best-build claim.

No universal best barricade verified yetThe official description names food, water and barricades, but it does not publish a complete cost, strength or placement table.

Use one repeatable supply check

  1. Start from the same apartment and write down the visible day, food count and stored water.
  2. Take one short route and record the item name, quantity and return time shown by the game.
  3. Repeat the route without changing the server or team size when possible.
  4. Separate a one-time pickup from a repeatable source before calling it a farming route.
  5. Reconnect once and check whether the stored supply, day and inventory persist.

How to compare a barricade

“Best barricade” depends on what the current build rewards: low material cost, high visible strength, quiet placement, coverage of a doorway or time bought during a hallway attack. Compare the same doorway with the same starting resources and record:

01CostVisible material or resource requirement.
02CoverageWhich entrance or opening the placement actually protects.
03DurabilityThe visible strength or time before the game shows damage.
04Noise and recoveryWhether placement, repair or replacement changes the next route.

Do not copy a generic “best barricade” list from another zombie game. The official Roblox experience is the authority for current prompts and values; this page records a method until a dated live test supplies a stable table.
