Top War: Battle Game How to Upgrade Guide
Although there are various different structures in Top War: Battle Game, there are four that you should continually prioritise when upgrading. These are the barracks, air base, navel base, and gold mine. The first three structures are your production buildings for your combat units while the gold mine is your primary sourceof funds for contsruction and training. Check out our How to Upgrade Guide to find out how you should proceed when upgradingStructure Resources
The structure level of a building indicates its level when you build it. The resources need for the structure level can be farmed from rebel armed forces and by searching the world map for gold mines. The merge level of each structure is higher than its build level.Merge Resources
Make sure you keep merge levels higher than structure levels, the only time you should focus on farming for structure level resources is when the merge levels are 3 levels higher than its counterpart. You can obtain merge resources from separatist regimes and by scouring the world map for oil fields.Force Combination Resources
More important than structure and merge resource levels is the unit force combination level which like the relationship between the structure levels and merge levels can also go three levels higher. The unit force combination refers to the land force, air force, and navy, of your army. You can obtain the needed resources for force combination from mercenary organisations and by farming lands in the world map.Research Center
You can keep track of the structure and merge levels of your buildings as well as your unit combination levels by tapping on your Research Center which you unlocked when you completed the tutorial. To determine the current levels you must deduct 1 from each category as each icon represents the next level of upgrade. The light-coloured icons indicate that you can upgrade them once you collect the required resources while blackened icons must be unlocked first or need the fulfillment of an upgrade.
