Mega Blast is a secret unlockable activated item added in Afterbirth.

Effects[edit | edit source]

  • Upon use, Isaac fires a giant, incredibly powerful blood laser, similar to the one used by Mega Satan, for 15 seconds.
    • The beam deals Isaac's current damage multiplied by 5 per tick.
    • The beam has enough power to push Isaac backwards while being fired, and will last between rooms, and across multiple floors.
    • While Mega Blast is being fired, Isaac cannot:
    • The laser extinguishes fires, detonates TNT, and destroys poop.

Notes[edit | edit source]

  • Picking up a Little Battery with this item will not fully charge it. Instead, it will add 3 to its charge, meaning that 4 batteries are required to fully recharge the item.
  • Using a 48 Hour Energy pill with this item will fully charge it.
  • In order to unlock Mega Blast, Mega Satan must be defeated with all characters including secret characters (The Lost and Keeper).
  • Afterbirth† Indicator.png Beating Mega Satan as Apollyon is not required to unlock this item.

Synergies[edit | edit source]

  • Homing Tears: Beam curves toward nearby enemies.
  • A Lump of Coal A Lump of Coal : Increases the damage of the laser the farther that it travels. Also colors the laser black and makes it wider as it travels.
  • Rubber Cement Rubber Cement : Beam bounces off walls like Brimstone Brimstone would.
  • Tiny Planet Tiny Planet : Beam rotates around the player like Brimstone would.

Interactions[edit | edit source]

  • My Reflection My Reflection : Causes the beam to curve while moving.
  • Proptosis Proptosis : The beam does massively increased damage at close range but does nearly no damage from afar.
  • Sharp Plug Sharp Plug : Fully recharges the item upon use at the cost of 2 hearts.
  • DLC Indicator.png Car Battery Car Battery : No effect.
  • Afterbirth† Indicator.png Void Void : Allows the item to be used every 6 rooms instead of 12 and batteries will fully charge the item.
