They Are Billions: Difficulty Level
Before you start the game, you can select your difficulty level. This is determined by the Score Factor and is expressed in a percent value. The higher the factor, the more difficult the game is. This, on the other hand depends on parameters you select, such as the type of the map, the duration of the match, density of zombies (number of the infected on the map). Match duration translates directly into how early waves of zombies start incoming. As of now, there are 5 durations, 4 maps and 5 types of density available. To unlock the second, third and fourth map, you have to beat the first map with score not lower than 20%, the second one with score of at least 60%, and the third one with score of 100%.
