Tale of Diep (ToD) is no longer under active development as a derivative of Diep.io and remains here as an archive, though spin-offs such as The Extended Tale of Diep remain active. For info on the successor to Tale of Diep, now an independent work called "A Tale Where Nothing Matters", visit its Discord server here.

A beast the lies in the heart of Somber Falls. The polygons will release it to hold against the Tank Empire. Unlike any other strong being seen, it can summon its own powerful polygons, Quasars.


The Industrian is a decagon boss that rarely spawns in the Realm, exclusive to Somber Falls. It is the most powerful polygon boss, equipped with a huge arsenal of weapons. It has an Annihilator cannon on top, 5 auto cannons on the body, 5 heavy auto cannons on the sides, and 5 minion spawners that summon White Destroyers and rarely the Quasars.

This boss will linger around the center of a superior polygon nest, which will be aided by the current polygon nest of any kind.

The penetration is twice as strong as the Dominator bullet, and same damage as a Dominator bullet. It reloads every 12 seconds. This bullet will also receive little knock back from anything but destroyer bullets. The range is 33% larger than a sniper.
