Diepio Classes

Tiers separate tank classes, organizing them by the characteristics of their barrel(s).

These tiers are represented in the Diepio Class Tree, shown to the right, which is a series of concentric rings containing every class in the game. It can be displayed in-game by pressing the Y key. In the direct center of the Class Tree is Tier 1, or Level 1. The first ring contains Tier 2 (Level 15) tanks, the second ring contains Tier 3 (Level 30) tanks, and the outermost ring contains Tier 4 (Level 45) tanks. Areas shaded black on the tree indicate an unavailable upgrade in that tier.

Interestingly, there is a recurring pattern of colors in the upgrade selection menu and the Class Tree. The first tank will always have a light bluebackground. The second will be green. The third will be red. The fourth will be yellow, and the fifth will be dark blue. Regardless of speculation, these colors do not seem to represent anything other than a simple order pattern to more easily discern tanks apart when quickly selecting an upgrade.

  • All Tier 4 tanks are at least 126 pixels wide, and at most 175.
  • The old Predator and X Hunter are still able to play on mobile.
  • There is a running theory that the background color of the upgrade icon corresponds to the base stat debuff it gets, as it typically matches the color of the respective stat bar.
    • There are several issues with this:
      • If the background color depended on the tank's stat debuff, there wouldn't be color variants, as seen in the Overtrapper, Auto Gunner, Streamliner, and Battleship, for example.
      • The stat debuffs aren't necessarily true; for instance, the Battleship may have a dark blue background, but with its notoriously fast drones, it certainly doesn't get a debuff to bullet speed.
      • In general, the theory can easily be debunked with simple Sandbox testing.
  • Acquiring level 45 requires you to get 23,536 experience.
    • In Free For All, Team DM and Maze, this is equates to:
      • 2354 Squares
      • 942 Triangles
      • 182 Pentagons
      • 24 Green Squares
      • 10 Green Triangles
      • Alpha Pentagons
      • Green Pentagons
      • 1 Boss
