|Defeat Mega Satan as every character|
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 backward while being fired and will last between rooms, and across multiple floors.
- The beam has spectral and piercing effects.
- The beam can be moved while firing in many angles diagonally.
- 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.
- A charged key will only add 3 charges as well.
- Using a 48 Hour Energy pill with this item will fully charge it.
- Mega Blast has an 80% decreased item pool weight, making it less likely to appear than other collectibles.
- To unlock Mega Blast, Mega Satan must be defeated with all characters including secret characters (The Lost and Keeper).
Synergies[edit | edit source]
- Ipecac: Massively increases damage, poisons enemies, and turns the beam dark red.
- A Lump of Coal: Increases the damage of the laser the farther that it travels. It also colors the laser black and makes it wider as it travels.
- Polyphemus: Quadruples beam's damage.
- Rubber Cement: Beam bounces off walls.
- Spoon Bender: Beam becomes purple and homing, although not very accurate.
- Schoolbag: Beam will continue to fire when switching to another active item. Other active items can be used while the beam is firing.
- Tiny Planet: Beam forms a large ring around the player and continues firing forward.
- Void: Allows the item to be used every 6 rooms instead of 12 and batteries will fully charge the item.
Interactions[edit | edit source]
- Angelic Prism: Laser beam will only split and change color when Isaac is directly against a wall.
- Godhead: Multiplies beam damage by 1.2, retains homing effect. The beam does not have a damaging aura.
- Incubus: Familiar fires normal tears while Mega Blast is in use.
- Soy Milk: Reduces beam's damage to Isaac's base damage.
In-game Footage[edit | edit source]
Trivia[edit | edit source]
- Mega Blast's collectible sprite is called 'Mega Satan's Breath' in the game files, which may be its initial name.
Bugs[edit | edit source]
Bug! If the player continues a run that was exited while Mega Blast was active, Isaac will retain the costume and animation of Mega Blast until the item is used again, but no beam will appear.
