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.

The War Machine is a multi-piece death machine designed for the purpose of killing small insignificant players. While its inventor was formerly unknown, at the time of its creation no one could even imagine who would create such a machine for such a purpose. We now know whose idea it was to make a weapon meant for nothing but death and desolation. Tanks shiver when the name War Machine is whispered or even mentioned. However, over the horizon they see it approach again, and they don't have that much time to prepare. Are you ready to take on the old world's fears, or fall back in a shroud of terror and wait for your demise?


War Machine in battle, with some Tears of Panzer. Art by Graviatar.

The War Machine is a Realm Boss that spawns in Neverest Mountains. It is made up of five very large tanks and one core. The tanks rotate around the core, targeting players that dare approach it. It has a massive arsenal, as there are many different weapon types spread around. This was the first creation of Dr. Lacus after he pledged allegiance to the Cult of Panzer. Created by Zathsu.

The Components

It is made of six separate parts, each with their own individual health pool, but the entire machine shares one Health Bar at the top of the screen. When a piece runs out of health, it blows up, dealing damage to players near it. After that, all of the pieces will re-structure themselves to be evenly spaced apart. The Core is impervious to damage before the five rotating segments are destroyed. The six components are:

  • The Core: The massive center that the other parts are attached to. It can also fire twin lasers that target separately from the yellow lasers on its center. These lasers will slowly increase in damage over time, but can be reset by dealing enough damage to The Core. Is completely Invulnerable until the five segments mentioned below are destroyed.
  • The Gatling: A tank attached to the Core with four thin barrels that aim at players. It shoots a RAPID, like almost stacked, stream of bullets at those who approach it. They don't do much damage, but inflict Panic for 5 seconds, and are the size of Gunner bullets.
  • The Spire: An Overseer-like turret that pumps out Drones that orbit the War Machine like a shield, or attack players. These drones are red and metal plated like the Machine itself. The summoning speed is about 120% of a normal Overseer. These deal moderate damage, have heavy knockback, and inflict Bleeding for 3 seconds on touch.
  • The Chainspike: A Griever hook that splits into three hooks seconds before making contact with the player its after. The two other chains go out in the respective diagonal directions next to the point, hitting more players. If a player is latched, they will be pulled in a bit, before being fired out as if a Lurker launched them.
  • The Seeker: A Tri Shot that shoots red missile shapes that will chase after players. They have a red circle 2x the size of a tank around their center. If a player enters it, the missile will stop homing, and start travelling straight forward. These missiles on contact with a player or object deal heavy area damage, and inflict Burning for 2 seconds.
  • The Slayer: At first it looks innocent and small, like a sword, but then it extends and four barrels stick out of it! They fire incredibly fast bullets in sync, creating a wall of shots for those in its path to dodge. These bullets don't do a lot of damage on contact, but each one inflicts Confused AND Unfocused for 3 seconds.


  • The first ever real boss created by Zathsu.
    • Because of this, it has no 'abilities' and is exceptionally simple in explanation.
      • Debuffs and slightly more complicated patterns were added later by Feb 19th, 2018.
    • This is also due in part to being a multi-tank mechanism, which has separate pieces that all have preset functions.
  • This boss has gone through many health buffs and debuffs.
    • Upon creation, the total health was 20,000.
    • It was then buffed to 45,000.
    • It was then nerfed to 35,000.
    • Mothership Game Mode was added, so we had a sense of health points again. Total was buffed to 70,000.
    • It was then nerfed again to 64,000.
    • A few days later it was made 93,000 health.
    • It then sat at 75,000.
    • It only currently sits at 112,000 with the health overhaul of April 17th, 2017.
    • After becoming a Realm Boss, its health was nerfed to 51,000.
  • The first of many mechanical nightmares created by Dr. Lacus. Laboratory Mode does not count, as that is a gamemode, not an enemy/boss.
  • It has a newer, upgraded version...
  • Multitool VII (in the Extended Tale of Diep) was the seventh prototype for the War Machine. The first six failed or were destroyed.
