Blue Bomber is Challenge #23 introduced in The Binding of Isaac: Afterbirth. The challenge is started as ??? with Kamikaze! Kamikaze!, Pyromaniac Pyromaniac, Mr. Mega Mr. Mega, and Brother Bobby Brother Bobby. No Treasure Rooms. The goal is to defeat Satan.

Difficulty[edit | edit source]

??? is blindfolded and cannot fire tears. Players will have to use Kamikaze! and bombs to defeat enemies, with Brother Bobby generally as a last resort. Because Pyromaniac prevents damage from being taken from explosions, players can use Kamikaze! whenever they please. Using it as an offensive weapon can be very dangerous, as the player will have to closely approach enemies, increasing the chance of taking damage.

As ???, health is crucial due to the absence and inability to obtain Red Heart containers. Any form of damage is threatening, as hearts may be hard to replenish.

Strategies[edit | edit source]

  • Finding an item which revives ??? as another character, like Lazarus' Rags Lazarus' Rags or Judas' Shadow Judas' Shadow will make the run trivial: After reviving ??? will be able to gain Red Heart containers, therefore heal infinitely as long as there are extra lives, effectively making him invulnerable. Added in Afterbirth †Clicker Clicker will also work, though the odds of getting it are small.
  • With Kamikaze!, rooms can be skipped without having to clear them. This can especially be useful against larger and more challenging rooms.
    • Broken Remote Broken Remote allows for essentially infinitely reusable teleportation, enabling entire floors to be skipped, except for boss fights.
  • The player should use bombs for boss fights or harder enemies. Due to Mr. Mega Mr. Mega, not only do bombs deal increased damage, but they also have a far larger blast radius.
  • By dropping a bomb then using Kamikaze! to propel the bomb towards enemies, ??? can safely deal damage from afar with relative ease.
  • Kamikaze! effectively gives ??? infinite explosives, so it’s a good idea to blow up rocks to look for Crawl Spaces, and ??? can search for Secret Rooms at no cost. Also, the player can blow up Tinted Rocks, Skulls, and Blue/Purple Fire Places, which may contain Soul/Black Hearts. However, be careful about blowing up Skulls before clearing a room, because they may contain Hosts.
  • Be careful about bombing objects that could deal damage to ??? upon destruction. It's risky to use Kamikaze! around Mushrooms since they may release damaging gas or around Polyps as they may explode into bullets. It may behoove the player to destroy these obstacles via bombs to prevent such a scenario from occurring.
  • The player should not replace/reroll Kamikaze! as without it, the challenge will be extremely difficult or even impossible. They should be very careful around Dice Rooms, Missing No. Missing No., and certain dice items.
  • Familiars and BFFS! BFFS! are useful in this challenge, since it allows the player to deal with enemies that are dangerous up close more easily.
    • BBF BBF and Bob's Brain Bob's Brain are especially useful as they gain increased damage from Mr. Mega, while Pyromaniac will protect ??? if they explode close by.
    • Bumbo Bumbo in his level 4 state allows the player to keep enemies at a distance while Bumbo chases them down and does contact damage.
  • The Polaroid The Polaroid is preferred over The Negative The Negative since the shield will trigger every time ??? takes damage, allowing him to get up close to spam Kamikaze! safely for a brief moment.
  • When fighting Mom, a reliable strategy is to stand in the corner and play defensive. Whenever she exposes herself from nearby doors, go to them and use Kamikaze! from the side. ??? cannot be hurt by her (and Satan's) stomping attack (see Pyromaniac Pyromaniac), but watch out for its knockback.
    • Due to the immunity to Mom's stomping attack, Mom's Toenail Mom's Toenail has improved usefulness.
  • Items that modify bombs, such as Bomber Boy Bomber Boy, Bob's Curse Bob's Curse, and Butt Bombs Butt Bombs are especially useful, as they provide a greater range for the detonation, a poison effect, and damage to the entire room, respectively.
  • Glitter Bombs Glitter Bombs provide an unlimited source of pickups, including Soul Hearts.
  • Gaining flight allows ??? to quickly navigate rooms, to avoid having to use Brother Bobby Brother Bobby to reach faraway enemies, and to better maneuver around for Kamikaze! usage.
    • Transcendence Transcendence, which grants flight, can be found in Secret Rooms.
  • Trinity Shield Trinity Shield, which is incredibly useful for blocking shots, can be found in Angel Rooms. Since ??? can't fire tears, focus on defending from enemy projectiles. This is especially useful in the battles with Mom's Heart/It Lives and Satan.
  • Sleeping in a bed will give 3 Soul Hearts.
  • Since ??? is unable to use Red Heart pickups, Dark Bum Dark Bum is extraordinarily useful as he gathers the hearts and converts them into Soul Hearts and Black Hearts, as well as the occasional friendly blue spider.
  • Added in Afterbirth †Camo Undies Camo Undies are especially useful. Every room entered will confuse enemies and with Kamikaze! they will not attack ??? as long as the fire buttons aren't pressed.
  • Acquiring Chaos Chaos makes this challenge far easier. Allowing bomb-related items such as Butt Bombs Butt Bombs and Sad Bombs Sad Bombs to spawn in Shops, Devil/Angel Rooms and as Boss rewards, these items allow Isaac to hit enemies passively from afar or use an unlimited Tammy's Head Tammy's Head-style effect, especially powerful when combined with Brimstone Brimstone.
  • Empty Vessel Empty Vessel is another great item that makes the challenge easier. You get 2 Black Hearts and its passive activates across the run, giving you flight and a 10-second shield every 40 seconds. Paired with The Polaroid The Polaroid shield already mentioned, you can activate Kamikaze enough to kill most bosses without taking any damage.
  • Censer Censer is useful for reducing the risk of being overrun by fast enemies, and makes it far easier to dodge enemy projectiles when weaving towards them.

Notes[edit | edit source]

  • If the Satan boss is somehow skipped, using I AM ERROR or Sacrifice Room's 12th activation, the golden door will not appear in the Dark Room Dark Room and upon killing The Lamb the completion trophy will still drop although this isn't recommended.
  • Converter Converter does not convert Soul Hearts into Red Heart containers; it just takes 2 Soul Hearts and gives nothing in return.

Reward[edit | edit source]

  • Gold Bomb
    Gold Bomb - Complete Blue Bomber (challenge #23).

Note that Golden Bombs have fixed appearances in certain room layouts even before this achievement is unlocked. The achievement simply allows them to spawn in place of other bombs, like Golden Keys.

Trivia[edit | edit source]

  • The title for this challenge is a possible reference to Mega Man, as he is commonly known as the Blue Bomber.
