After being delayed for years, it finally has been added to diep.io a while before Halloween, this version replaces the original diep.io.

• Glider is the newer than Auto Tank.

Miscellaneous

• There is now a cyan "Log In" button and a yellow "★ Shop" button.

  • Dev: Super Saiyan Mode: Gives the player 160 skill points and sets the skill point cap to 20.
  • Dev: See Whole Map: Will increase FoV to the point the entire map is visible and sets the camera to the center.
  • Max Level: Now can set the player all the way to level 200.

Protector

The Protector looks like an Overseer but with 3 small but very spammy barrels. The barrels are extremely similar to the Gunner Dominator's. Its spawners spawn uncontrollable swarm drones, slightly larger than normal swarm drones, which orbit the player unlike normal swarm drones, and last longer than normal swarm drones. It can have up to 20 uncontrollable swarm drones if there are 0 points on reload.

"Spike"

This looks exactly like the Spike but invisible. It only has 1 skill: Movement Speed. It has infinite health and 0 body damage. It can bonk and push things and Crashers can see and chase it.

Hexagon

A new polygon is added - Hexagon. It gives 1500 XP, and has 1500 HP. It takes 1715 hits from a Basic Tank with no points on Bullet Penetration or Bullet Damage to kill it.

It has 16 Body Damage.

It is extremely rare. It is not recommended to kill it.

Before September 19, 2025, it was Square sized, took 3 hits from a Basic Tank with no points on Bullet Penetration or Bullet Damage to kill it, and it had 10 HP, 8.4 Body Damage, and gave 25 XP. It was later buffed to 800 HP, 800 XP and 16 Body Damage. It would be buffed again.

Trivia

• Before September 23, 2025, on tablet, the joystick settings and class tree button will appear, but the joysticks will not load, and the upgrades and skill points will not be the mobile version.
• On phone, if the player does not use the joysticks, they will face directly right.
• The only region here is Atlanta.
• There is no party link button.
• Shotgun is the only Tier 3 Tank without any achievement associated with it.
• The player can see all achievements, with earned ones in color, by moving their mouse to the right side of the screen.
• Occasionally the game mode and region buttons will disappear.
• Team names in leaderboard and announcements are not Caps Lock.
• Players are not immune in bases anymore.
• The Arena Closers could instantly wake up and start killing players immediately.
• Domination can have different amounts of teams.
• When a server starts, the starting polygons spawn every frame instead of immediately spawning.
• The "Left" and "Right" joystick settings do not affect anything.
