Source listed July 12, 2026. The core city, missile, and attack-reward loop comes from the official Roblox description. The upgrade priority is a conservative reading of that loop and current guide sources. It was not tested in game by ObbyList.
THE CURRENT ROUTE
Choose the next upgrade from your current bottleneck
- 1
Build enough city income to keep early purchases moving.
- 2
Improve missiles when attacks are too weak or slow to return useful rewards.
- 3
Return to city upgrades when cash flow becomes the main blocker, without following a fixed ratio.
OPENING LOOP
Use city income to keep early purchases moving
Roblox describes two connected systems: building and upgrading the city, then improving missiles and earning rewards by destroying rival buildings. The current guide support points to city income first because it pays for later choices. Stop adding city upgrades when the next useful purchase is affordable and weak attacks, rather than cash flow, become the obvious limit.
This is not a fixed timer or spending ratio. Watch the result after each purchase. If cash arrives too slowly to continue, the city still needs attention. If money is available but attacks take too long or return too little, missile strength is the more direct problem.
SWITCHING RULE
Move spending toward the current bottleneck
Upgrade missiles when weak or slow attacks prevent you from earning useful destruction rewards. Return to city upgrades when the economy cannot replace spending or support the next missile purchase. Alternating for a reason is better than following one permanent half-and-half split whose numbers may not match the current server.
Compare one change at a time. A city upgrade should improve the cash problem you identified, while a missile upgrade should improve the attack problem. If several upgrades are bought together, it becomes harder to learn which system was actually holding back progress.
UNCONFIRMED NUMBERS
Use the live prices and descriptions as the final check
The checked official sources do not publish exact missile damage, cooldown, price, efficiency, or one universal opening. This page therefore gives a decision rule rather than a copied stat table. Read the current upgrade panels, identify whether income or attacks are slow, and spend where the next purchase removes that limit.
PURCHASE QUEUE
Know what the next upgrade is meant to unlock
Before spending, name the next purchase after it. A city upgrade may be worthwhile because it shortens the wait for a needed missile improvement; a missile upgrade may be worthwhile because stronger attacks return rewards that fund the city. When the purchase has no connection to the next bottleneck, save until the live prices make the choice clearer. This avoids random alternating while keeping both halves of the official loop connected.
