Notes[ | ]

  • While Mama Mega! opens the paths to Boss RushBoss Rush and the ?????? after the time limits expire, there are still some things to be aware of:
    • The Boss does not need to be defeated before entering these doors.
    • It will also open the Boss Rush / ?????? entrance room door if it is activated after Boss Mom ingameMom or Boss Mom's Heart ingameMom's Heart/ Boss It Lives ingameIt Lives has already been defeated.
    • Leaving the Boss RoomBoss Room (via teleport or entering a Devil RoomDevil Room/Angel RoomAngel Room) will close the doors.
    • Leaving the Boss RushBoss Rush room or ?????? entrance room will also close the doors.
    • Does not open the Boss Rush door from the inside.
    • (in Repentance) Does not open a path to ?????? if used in the room on the other side of the flesh door in MausoleumMausoleum / GehennaGehenna II.
  • Entering a room with an angel statue while the effect is active automatically initiates a fight with an Angel.
  • Does not kill enemies that are immune to damage while entering the room, such as Lil' Haunts.
  • If used before the Boss Ultra Greed ingameUltra Greed fight begins, it will deal no damage to Ultra Greed, as he is invulnerable for the first few seconds upon first entering his room. However, it will still break obstacles as usual.
  • When used in Greed mode, it will only activate once for the main room (as opposed to once per wave, in a similar fashion to a standard run). Therefore, its damage potential is maximized if used after all the monster waves have spawned for the current floor.
  • Does not open the door to Mega Satan Head ingameMega Satan in Dark RoomDark Room or ChestChest, nor does it open (in Repentance) the flesh door at the end of MausoleumMausoleum / GehennaGehenna II..
  • (in Repentance) If used in DownpourDownpour / DrossDross II, the entrance to the Mirrored World will be destroyed, making it inaccessible.
    • If used in the Mirrored World, it will destroy the exit, which, on top of making it impossible to leave, will then cause Isaac to take damage and die.
    • This can be avoided by entering and immediately leaving the room before the shockwave reaches the mirror.
  • (in Repentance) Only works on a single floor of the Ascent
