This project came to life when the author’s yearly April Fools at the Advanced Rescue Team Discord centered around the idea of a dungeon the player could not finish because it just kept going on forever.

But what if we tried to make it good?“ Well, 4 months of polish, balancing and a scoring system later here we are.

Pokemon Mystery Dungeon Infdev offers a competitive single-player experience, a lot of quality-of-life the vanilla game needed and updates to existing mechanics as well as
bug fixes for issues the vanilla game had.


  • The very first infinite dungeon out there
    • Your enemies scale with your dungeon progression
    • Every run gets a score and the end to tell you how well you did
    • A rank based on your score where your rescue rank once was.
  • Updated mechanics
    • Updated status effects that now truly impact your gameplay
    • Uniform Item pricing
    • Gummies that give experience
    • Total control over your partner
    • Updates to some traps, moves, Pokémon, and their walk data
  • Quality-of-life
    • Quickly select your moves with L+D-Pad and use them with L+A
    • Weather damage does not interrupt your movement
    • Your mailbox acts as a Kangaskhan Statue
    • Walking speed inside the dungeon is either vanilla fast or even faster
  • Custom fun
    • There is a lot of new stuff here like music, sprites, items and custom code
    • An alternative patch if you want to change up your runs
    • A “choose to be the enemy“ feature that lets you use the Transfer Orb on your team
