Areas

Nuclear Throne takes you through a series of areas.

''The way you progress through the areas is linear, you start in a normal world which is three levels long, at the last level the area boss will spawn then you enter a transition area which is only one level but the level itself is larger. After that you enter another world, and the cycle repeats itself.''

''Difficulty is the number of portals you entered, it determines the amount of enemies spawning in the area and what kind of weapon you get in that area. Entering a Crown Vault or the Sewers Secret Area also counts as entering a portal and increases the difficulty by one, so you get better weapons faster but there are more enemies.''
