Island Raiders Raiders Building Upgrade

How to upgrade buildings and the order of upgrading buildings has always been a big problem for players, and this upgrade strategy is to help players solve this problem, make rational use of resources and gain greater advantages.

The island attacker explored the island.

Building upgrading is mainly divided and upgraded according to the cost of different stages. For example, some arms cannot be upgraded until they reach a certain level, so the corresponding upgrading strategies, arms collocation and development methods are different at different stages.

1-6 command

Upgrade order:

Radar research institute warehouse, temple defense facilities, treasury resource facilities

The initial map is still relatively small, so players must upgrade the radar as soon as possible, open the map and find more resource islands as soon as possible. Then upgrade the types and grades of arms through the combat academy to grab the resource island.

7- 10 level command

Upgrade order:

Institute treasury = radar defense facilities, temple warehouse resources and facilities

During this period, the institute should be upgraded first, followed by the vault and radar, and the role of the vault emerged from this stage. I suggest you do the first three things before you reply. It's not too late to consider upgrading before upgrading the warehouse.

1 1- 12 level headquarters

Upgrade order:

Defense facilities in the basement of the institute = radar resource facilities in the temple warehouse.

At this stage, the first task is to upgrade the landing craft to 12 level, so that it can carry two tanks or four heavy machine guns (fat men), five warriors (savages) or eight rocket launchers (MM), thus greatly improving the offensive capability, so the research institute should be upgraded as soon as possible.

13- 14 level headquarters

Upgrade order:

Treasury defense facilities = research institute = temple warehouse acquisition facilities radar

After upgrading the vault, we will do our best to defend ourselves, especially the giant cannons and rocket launchers. The institute can be upgraded only by stealing air. After all, with the support of 12 6 class boats, the level of arms is no longer the decisive factor.

From the above four different stages of building upgrading smoothly, the development direction of each stage is different, some are mainly resource development, and some are mainly military building development.
