RoFront building reference
Compare Cities, Factories, Ports, Defense Posts, Silos and SAMs by purpose, placement and recorded gold costs.
SOURCES REVIEWED 21 OCTOBER 2026
Build for the constraint in front of you: troop capacity, income, access or survival.
Roles and recorded prices
The prices below are examples reported in the October 19, 2026 guide. Costs can rise with construction and upgrades. K means thousand gold and M means million gold; check the current tooltip before spending. These are not guaranteed starting prices.
7 building types
| Building | Recorded gold | Purpose and placement |
|---|---|---|
| City | 125K–1M | Troop-cap growth. The guide reports +25,000 cap. Keep useful Cities on land you can defend. |
| Factory | 125K–1M | Income through building connections and traffic. In NoobBlox’s October 18 recorded run, nearby opponent-owned buildings can also connect. Inspect nearby infrastructure; exact network distance is not verified. |
| Port | 250K–1M | Coastal trade and Warship access. Place on an appropriate shore and check the water beyond it. |
| Defense Post | 50K–250K | Border fortification. The guide reports 30-tile coverage, with attacks costing 5× troops and 3× time in its covered area. |
| Missile Silo | 1M | Prerequisite for nuclear strikes. Consider reach to the target and protection for the Silo. |
| SAM Launcher | 1.5M–3M | Anti-bomb protection. The guide reports a 70-tile range. Coverage is not a promise that every weapon is interceptable. |
| Warship | 250K–750K | A naval unit ordered through the coastal system, included here for budgeting. Contests transports and hostile sea control. |
No matching building. Try “city”, “port” or “income”.
A practical purchase decision
Troops capped, gold available: inspect a City. Spending delayed by weak income: inspect a connected Factory. No route across the water: inspect the coast and Port options. A costly border is taking pressure: inspect Defense Post coverage. Nuclear threats threaten a dense cluster: inspect a SAM and whether its coverage reaches those assets.
This is a conditional decision guide, not a universal build order. For example, a cheap Factory on an exposed border can be a worse next purchase than protecting the connected economy you already own. The building’s job and its location both matter.
Place and upgrade deliberately
- Choose your own suitable land and open Build.
- Read the selected structure’s current cost, placement restrictions and coverage preview where shown.
- Confirm you can afford the purchase without assuming a recorded range is your exact price.
- Place it and inspect the expected result: extra cap, a connected network, a coastal facility or a coverage ring.
- For an existing structure, inspect its upgrade action. NoobBlox demonstrates applying an upgrade to the existing building; check the changed level and price before repeating.
If placement fails, recheck land ownership, shore requirements, gold and the on-screen prompt. We have not established hidden spacing rules, so moving the cursor at random is not a verified fix.
Capture or destroy the infrastructure?
The recorded strategy values taking areas with Cities and Ports intact. Those structures can strengthen your position after capture. A nuclear strike may remove a difficult concentration of defenders, but also destroys assets you might have kept. Compare the immediate military obstacle with the infrastructure you want to acquire before choosing a target.
