Binding of Isaac: Rebirth Wiki

Demo Man is challenge #9. Isaac starts off with Collectible Dr. Fetus iconDr. Fetus, Collectible Remote Detonator iconRemote Detonator, and the Match StickMatch Stick trinket. The goal is to defeat Boss Mom's Heart ingameMom's Heart or Boss It Lives ingameIt Lives. This challenge is available after unlocking Dr. Fetus.

Difficulty[ | ]

The only weapons are BombBombs, which can harm Isaac if he's too close. The Collectible Remote Detonator iconRemote Detonator works on the Dr. Fetus bombs that replace tears but does not prevent them from exploding after their fuse runs out.

Match StickMatch Stick causes more bomb drops than other drops, such as Red HeartHearts or ChestChests. Since there is an unlimited supply of bombs, this can be a hindrance.

Strategy[ | ]

  • Since every run starts with Dr. Fetus, there is a virtually infinite supply of bombs. Anything that would normally use bombs can be done by attacking.
  • While Remote Detonator does not prevent bombs from detonating, using it will still cause them to explode prematurely.
  • Shot speed will cause the bombs to launch faster and farther.
  • Flying can help with avoiding explosive damage in tight quarters. This can make Collectible Lord of the Pit iconLord of the Pit or Collectible Spirit of the Night iconSpirit of the Night more valuable.
  • The infinite bombs allows testing every wall for Secret RoomSecret Rooms and Super Secret RoomSuper Secret Rooms. They also enable Isaac to escape rooms without clearing them by blowing open the doors.
  • Acquiring explosion immunity via items such as Collectible Ipecac iconIpecac, (except in Rebirth)Collectible Host Hat iconHost Hat or Collectible Pyromaniac iconPyromaniac make this challenge significantly easier. Ipecac immunizes Isaac only to the bombs fired by Dr. Fetus, however, not their possible fragments or other explosions.
  • If one manages to acquire (in Repentance)Collectible Rocket in a Jar iconRocket in a Jar, this challenge will be made easier, as the rockets travel linearly and explode on contact, making self-damage less likely.

Placed Bombs[ | ]

  • Match StickMatch Stick causes more bomb drops than other drops. Since regular bombs are more powerful than the Dr. Fetus bombs, this can be a boon. Dr. Fetus bombs can blast obstacles and walls, allowing placed bombs to be saved for combat.
  • Combined with the Collectible Remote Detonator iconRemote Detonator, more control can be had over placed bombs and can lay traps with them. This is especially useful during boss fights with invincibility periods, such as Boss Mom's Heart ingameMom's Heart and Boss Pin ingamePin, as multiple placed bombs can be laid near the boss's spawning point and detonated all at once.
  • If a placed bomb is misplaced, they can be moved by walking into them. Placed bombs will not explode until Remote Detonator is used, so Isaacs can move out of the way of explosive damage.
  • It is possible to drop the Match Stick by using Ctrl(PC), R2(PS4), R2 + RT(Xbox) or ZR(3DS, Switch).

Trivia[ | ]

  • This challenge is a reference to Team Fortress 2's 4th class, the Demoman. The Demoman uses various bombs as his choice of weapons, similarly to how this challenge is played.
