In RPG and roguelike games, generally a level refers to when you gather enough of a resource through gameplay to reach a threshold where you get a notification and a chance to improve your character by boosting stats or picking abilities. In many survivors-likes, when you level or fill up whatever bar you are filling, you are presented with items and weapon upgrades instead of skill trees and passive perks, but they function to make a build. We try to refer to the areas play takes place in as maps or stages to avoid confusion.
