The I.D.P.D. Headquarters is a loop-exclusive secret area. It consists of three full stages, the first two being standard enemy stages and the third being a spacious boss stage. In the first two stages, the only enemies which spawn are I.D.P.D. troops, as well as I.D.P.D. Vans and Elite I.D.P.D.. Since the area is entirely I.D.P.D., no Rads are dropped (unless the player is using Melting). The third stage is home only to the Captain, a secret boss whose difficulty is comparable to that of the Nuclear Throne. Beating the Captain will end your run.

How to enter the I.D.P.D. HQ

To access this secret area you have to first loop the game. Then press "E" on the I.D.P.D. Van while it's unloading I.D.P.D. units. That will open a blue portal leading to the I.D.P.D. HQ.



Trivia Edit

  • Rich vegetation and clean white color of this area symbolize that it's not affected by the apocalypse.
  • There's a diamond symbol that repeats itself on the walls, the I.D.P.D. Vans, the Captain's forehead, desk and on the floor of her office. A similar symbol can be seen in the Palace and on the Throne itself, it also resembles the Proto Statues. What the symbol means and how are all these things connected is yet a mystery.
  • The I.D.P.D. Headquarters' theme is "Beyond The Portal".
  • If Rogue enters the I.D.P.D. Headquarters, a music track will play unique only for her. It's a piano version of the I.D.P.D. Headquarters theme. The song is titled "The Place I Once Called Home".
