Radioatividade
From Rival Regions Wiki
A poluição radioativa da região tem influência na forma natural da regeneração da energia de todos os jogadores na região. Ocorre quando algum jogador utiliza Mísseis balísticos em guerras próximas à região.
Every epicenter extends its pollution to the other regions, that are located in 1.500 km radius. You can see the summ of epicenter and extended (acquired from another epicenters) pollutions on the region page.
Every 120 points of damage, dealt by using Ballistic missiles add 1 point of pollution to the epicenter.
Energy influence
Every point of pollution adds 0.5% to the time, needed for Energy to restore in natural way.
Cleaning
You can use Antirad and clean the pollution in any epicenter or pass the law.
You can see all active epicenters here.
