Teleport 2.0 is an activated item added in Afterbirth.

Effects

• When used, teleports Isaac to the next room that has not been explored yet.
  • The room that you are teleported into will be touching an explored room, if applicable.
  • When used in a room with enemies in it, it will teleport Isaac back into the same room.
  • The order of types of rooms you will be teleported into is predetermined, first available on this list chosen:
    • Grave Room.
    • Normal rooms.
    • Boss Room.
    • Super Secret Room.
    • Shop.
    • Treasure Room.
    • Sacrifice Room
    • Dice Room.
    • Library.
    • Curse Room.
    • Mini-Boss Room.
    • Challenge Room / Boss Challenge Room.
    • Bedroom.
    • Arcade.
    • Vault.
    • Secret Room.
    • Devil Room / Angel Room.
    • I AM ERROR room.
  • With every room above on the level mapped, Teleport 2.0 will keep you in the I AM ERROR room.
  • You cannot teleport to Crawl Spaces, the Boss Rush room, Blue Womb entrance or Mega Satan.

Notes

• In Cathedral or Sheol, using the I AM ERROR room exit will bring Isaac to The Chest or Dark Room respectively.
  • This can still be done even if Isaac has the wrong corresponding item (Polaroid/Negative) for that floor.
• On The Chest or Dark Room, Teleport 2.0 will teleport Isaac to the the devil/angel room instead of the I AM ERROR room.
• On The Void, using Teleport 2.0 in the I AM ERROR room will teleport Isaac to The Void again, allowing you to restart the floor. The floor generated contains new rooms and enemies. This can be done multiple times.

Synergies

• The BatteryActivated Items can be "overcharged" to allow for an additional use.: Having two charges by the end of the floor can guarantee getting to a Devil/Angel room and I AM ERROR, assuming the secret rooms have been explored.
• Blue MapShows secret and super secret room locations on the map./ Spelunker HatReveals type of adjacent rooms, including location for secret rooms and super secret rooms.: Allows you to know the location of Secret/Super Secret rooms.
• Charged BabyA familiar that drops a Little Battery every 4 rooms. Has a small chance to freeze all enemies in the room when hit.: Leaving the batteries it generates around the floor allows you to save them up and have multiple charges to use at the end of the floor once everything is explored, maximizing the chance of getting to I AM ERROR.
• EucharistAn Angel Room door will always spawn after every boss fight, excluding the first floor and floors after Utero II/Womb II.: Allows Isaac to visit the Angel Room without the use of Teleport 2.0, allowing reliable passage to I AM ERROR rooms.
• Goat HeadA Devil Room / Angel Room Door will always spawn after every boss fight, excluding the first floor and floors after Utero II/Womb II.: Allows Isaac to visit the Angel/Devil Room without the use of Teleport 2.0, allowing reliable passage to I AM ERROR rooms.
• The MindGrants the combined effects of the Blue Map, Treasure Map, and The Compass, revealing the floor layout and all special rooms, including Secret Rooms and Super Secret Rooms.: Allows Isaac to know the location of all rooms on the floor, including the Secret/Super Secret Room.
• X-Ray VisionReveals and opens all Secret Room and Super Secret Room entrances.: Allows you to find the location of Secret/Super Secret rooms.

Trivia

• Teleporting to the I AM ERROR room when all rooms on the map are explored is a reference to the error the item would otherwise cause.
  • It is as if the item is saying "ERROR, there are no more unexplored rooms left."
• This item is one of the two reliable ways to reach the I AM ERROR room in game, the other being the Blank Card + ? Card interaction—another paradoxical situation.
