Digimon Story: Time Stranger features an almost infinite amount of ways to gain EXP, money, and new Digimon. Perhaps the most fun of these methods comes in the form of the game’s Outer Dungeons, hidden rooms throughout the game which present the player with unique challenges to overcome in exchange for rewards. Because the Digimon that players will earn from these dungeons are almost always powerful for the point of the game when you can earn them, it is highly recommended that players search for them. Of course, that can be easier said than done as some of these rooms are well hidden. If you are a player searching for them then please read along with this guide showcasing the location of every Outer Dungeon in Digimon Story: Time Stranger.
If you spot any issues with this guide feel free to report them to me either on Reddit or the Raider King Discord.
Digimon Time Stranger – All Outer Dungeon Locations
Outer Dungeons will not spawn until you have visited the Digital World for the first time. Once there you will begin to see them in the various locations and towns you visit throughout your journey.
This guide will highlight the Outer Dungeons in the order upon which you visit areas, which oddly does not match the actual numbering of the Dungeons as some of the earlier numbered ones do not appear until later areas of the game.
Once you have found an Outer Dungeon you can play it as any time from the Theater.
