Hard mode

From Binding of Isaac: Rebirth Wiki
Jump to: navigation, search

Hard mode changes the gameplay compared to Normal in some ways to make it more difficult. When playing in Hard mode, a small red pentagram (Hard mode only) appears on the HUD, below the pickups.

Differences[edit | edit source]

  • 2-3 more rooms generate each floor.
  • Certain "easy" room layouts cannot generate, making difficult rooms more common.
  • Enemies have a base 20% chance to become Champions instead of only 5%; additionally, they only award pickups 33% of the time.
  • Hearts are 66% less likely to drop after completing a room.
  • Only champion bosses will drop hearts; normal bosses will not.
  • Floors are more likely to have curses.
  • Floors are more likely to be replaced by their alternate versions (e.g. Necropolis Necropolis or Added in Afterbirth Dank Depths Dank Depths instead of The Depths The Depths).

Trivia[edit | edit source]

  • Before update 1.03, the reduced drop-rate affected all pickups (not just Red Hearts).
  • Godhead Godhead, Added in Afterbirth †Smelter Smelter, and Added in Afterbirth †Marrow Marrow are the only items that require playing Hard mode to unlock, with every other unlock being co-op babies.
  • Godhead Godhead's unlock requirements were extended in the Afterbirth DLC (and further extended in the Afterbirth+ DLC) due to the addition of more completion marks, but it can still be unlocked in the base game using the same method.
