Twin Hammer (ツインハンマー Tsuin Hanmā?) is a sub-boss that appears in Sonic the Hedgehog 3. It is encountered in the end of Launch Base Zone Act 1 and takes six hits to be defeated. When playing as Sonic and/or Tails the player faces a single Twin Hammer, but when playing as Knuckles, the player will face two Twin Hammers.

Twin Hammers are mass produced circular robots created by Dr. Robotnik, which have two swinging spiked balls as its main weapons, which are attached with two smaller balls. They are stored in yellow metallic crates in the Launch Base Zone.


Sonic and Tails' Version

Inside the last tower section of Launch Base Zone Act 1, Dr. Robotnik is carrying a yellow crate below the Egg Mobile when he notices Sonic and Tails, and escapes upwardly. After exiting the tower section, Knuckles throws a bomb into the tower, that makes it crumble. After Sonic and Tails get out of the tower, they follow Robotnik into another building, where the doctor releases the Twin Hammer from the crate and escapes from the arena.

From the beginning, the Twin Hammer will follow the player while rotating its spiked balls. It will sometimes take a short break and then repeat the same pattern. This is usually the best change for the player to hit it. However, once the player does a Spin Jump, the Twin Hammer tries to retreat further away so it cannot get hit. The player therefore has to be close enough to reach the Twin Hammer before it retreats to a safe distance.

The Twin Hammer requires six hits to be destroyed. Hitting the Twin Hammer three times will destroy one of its spiked ball attachments. Hitting it the last three times will destroy the other spiked ball and the Twin Hammer itself.

Knuckles' Version

Not messing around

Knuckles's fight against two Twin Hammers.

In locked-on version of Sonic the Hedgehog 3 & Knuckles, Knuckles enters a different section due to him destroying the tower section earlier. After going above the ruins of tower, the player will scale through the walls to find a hole in a higher wall leading to another part of the base. There, Knuckles ends in a pit where he is faced by two Twin Hammers, making it more difficult to proceed.

During the battle. Knuckles' reduced jump height makes it impossible to reach the Twin Hammers when they are high up, so the player must wait until the robots are very low before he can land a hit. The player can also use climbing to reach the Twin Hammers easier. Both Twin Hammers take normally six hits and after destroying them, the floor crumbles away and Knuckles drops to a lower level where the Signpost appears.


  • The battle can be made easier to fight as Hyper Sonic or with a Lightning Shield as Sonic because of the possibility to do double jump.
  • Later in Launch Base Zone Act 2, several yellow metallic crates (which might possibly contain Twin Hammers) are seen as platforms where pulleys are attached to.
