Career Rank

Rank is a buying/experience limit. You start at Rank 1 with only the Dart Monkey (in BTD4 & BTD5), the Dartling Gun (in BTD4), and the Spike Factory (in BTD4). A new rank is awarded by earning the certain amount of XP. You can instantly unlock all upgrades, towers, and game modes by purchasing the Rank 34 Premium upgrade in BTD4 and BTD4E.
