建築
建築 是Rival Regions地區中最重要的特色，對玩家有重要的影響。
Contents
Military academy (MA)
此建築能影響該地區的初始攻擊傷害值：等級越高，由該地發動的陸海戰的初始攻擊傷害值就越高。軍事學院也會影響 戰爭傷害值。每個人都能蓋軍事學院，但是必須符合以下條件：
Every player can build MA only once a day. MA level is counted as a sum of all contributions for the last 14 days. That allows to avoid endless accumulation.
Hospital
Every building, except for MA is build by passing laws in parliament and spending money and resources from the budget. Every building type has its own price. Hospital level influence its region Health index. As you know, speed of Energy recovery depends on this index.
Military base
Military index depends on Military base level Your damage in wars depends on this index. As you know, every type of weapon has its α-damage, Military base, with other variables such as perks can increase this damage. You should see damage formula for more info.
School
This buildings determines Education index, which determines the speed of learning new perks.
Missile system
This building lowers damage in Ground and troopers wars in case if defending Missile system level is higher than that of an attacking side.
雙方飛彈系統差距最大只會考量到300。比如攻擊方為1000，防守方為1350；防守方所得到的防護跟1300所得到的值是一樣的。
You should see damage formula for more info.
Sea port
This building can be built only in regions with sea access. Just like Missile system, it can lower attacking side damage in Sea wars.
Power plant
This building provides independent regions or states with electricity, that is needed to power other buildings. You can see Power plant output info on state page. In case of shortage of power all buildings in the state/independent region will work with a penalty.
For example, if state buildings require 10.000 Megawatts but Power plant output is only 5.000 Megawatts all the buildings in this state will be performing at 50% of their level, excluding Military academy and Power plant.
Spaceport
This building determines the time needed to travel to/from the Moon.
Airport
Decreases (unlike Missile system) attacking side damage in Ground and Troopers wars in case of positive difference of Airport levels. Just like with Missile systems, only difference up to 300 points is taken into account. You should see damage formula for more info.
Airport building also speeds up travel process and lowers cost of delivery of weapons and items when donating them.
Can be built only on Earth.
Refill station
Can be built only on the Moon.
Just like Airport, speeds up travel process and lowers cost of delivery.
Housing fund
Determines Development Index of the region. Self-sufficient in terms of electricity and has no effect on initial defend damage and Index 11.
Private buildings (houses)
Every player can built his own private building. To build your house you should click + near building icon in your profile (under your avatar).
You can only have one house in the game. You can start building your house only in you residency region.
Top level of this buildings is limited to 99.
In case of losing in Ground war level of every house in this region decreases by 10%. In case of relocation it will lose 5%.
House level increases you storage capacity, lowers the time needed for new perks to be learned.
Cost of private houses
Up to level 10 you will need:
Level*1 G
Level*200.000.000 $
Level*10.000.000 Kg of ore
Level*10.000.000 Barr. of oil
Level*10 Pcs. of diamonds
從11升到99需要：
Level*1 G
Level*600.000.000 $
40.000.000 Barr. of oil
40.000.000 Pcs. of diamonds
Level*50 Pcs. of diamonds
Initial defence damage
Buildings also determine damage points which will be assigned to the defending side at the start of the war, coup or revolution. Initial defence damage allows you to defend regions more effectively. This damage is proportional to the sum of real (with Power plant penalty, if there is one) levels of the following buildings:
(Hospital + 2*Military base + School + Sea port (if there is a sea access) + Missile system + Power plant + Spaceport + Airport (or Refill station on the Moon))*50000
Additional indexes
Additional Indexes 11 are allocated to top 5 regions with the highest sum of buildings levels (all, except for Housing fund and Military academy) on Earth and 1 on the Moon.
