Blow Up The City Cash and Robux Spend Order

This tool is the spend flowchart for Blow Up The City. It does not invent restock timers or HP. It puts the live shop in an order that matches the airstrike tier list and the gamepass tier list. Use it before you open Robux and before you dump a first paycheck into Nuke.

If the skyline in front of you is already glass, this page cannot help you. Hop or open a private server, then come back.

Cash order (no Robux)

1. Repeatable bomb. Short restock, radius that covers two lots. This is S-tier because it buys the next shot. Targeting: how to destroy buildings.
2. Attack Heli once you can see a street or the train. Gun run, cash only. Guide: how to use Attack Heli.
3. Tornado or Earthquake when a district of walk-ups is still standing. Wide tools, same job, different silhouette — disasters.
4. Nuke when you can afford to miss and the cluster is still a cluster. Not for one hut. Not for ash.
5. Stop. Do not buy a second spectacle because the first one looked good in a screenshot.

Cash loop reminder: destroy standing mass, bank, upgrade radius. How to earn cash is the prose version. Cash runs is the server version.

Robux order (optional)

0. Nothing. Finish one vanilla city. Getting Started is cheaper than every pass.
1. X2 Cash — 99 Robux. The only pass that accelerates the loop. Buy if you already like the game.
2. Unlimited NPCs — 94 Robux. Crowd slider for private showcases. Not a farm by itself.
3. AC-130 — 149 Robux. 30mm toy after Attack Heli proved you want a gunship. How to use the AC-130.
4. ICBM — 199 Robux. From-space circle. Same waste rule as Nuke. How to use ICBM.
5. Unlimited Cash — 320 Robux. Sandbox skip. Fun on a private intact city. Teaches nothing on a public crater.

There is no bundle. Unlimited Cash does not include AC-130 or ICBM. Anyone selling pass unlocks is not Airstrike Industries. Codes still grant none of this.

Decision table

You see…	Spend
Fresh 2×2 of towers	Mid bomb, then Nuke if you can miss
Long walk-up street	Attack Heli (cash) or AC-130 (Robux)
Whole neighborhood up	Tornado or Earthquake
Bridge with both banks	Wide bomb or Nuke
Train beside houses	Attack Heli / AC-130, not ICBM
Scorched crater	Hop. Spend nothing
You like the loop and keep playing	X2 Cash
You want a private thumbnail	Unlimited NPCs + private server + any 1.5 tool
You want to skip farming	Unlimited Cash, and admit it is a skip

The airstrike planner asks mass / server / money. This page is the shop order after those three answers.

Saturday rule

Update 2 is teased for 12 September 2026. Do not pre-buy ICBM “for the patch.” Do not save cash for a name that is not in the shop. Play 1.5 with this order until the Roblox description actually changes, then rebuild the table from evidence.

If a new cash strike appears, slot it by shape: line with Attack Heli, circle with Nuke, wide with weather. If a new pass appears, slot it as economy (like X2), crowd (like NPCs), or toy (like AC-130 / ICBM). That is the whole system.

What not to spend

• Robux on a public crater.
• Nuke on a leftover hut.
• ICBM because Nuke felt small on ash (ash is small).
• Unlimited Cash as a tutorial.
• Scripts that “unlock the shop.” None are listed for this universe.
• Fake codes from other city games.

Spend on standing mass. Everything else is a trailer. When you are unsure, fire the cheap bomb. The expensive button will still be there after the cheap one pays.
