Deals a large amount of damage to all enemies in a room.

A remnant from when the Gungeon was being built. Gungeon architects would use these artifacts to quickly make their way through Gundead infested chambers. Though this one has lost a portion of its power to the ages, it is still a potent weapon.

Bracket Key is an active item.

Effects[ | ]

  • Deals 150 damage to all enemies in the room.
  • Prevents additional enemy waves from spawning when used.
  • Increases curse by 1 while held.

Notes[ | ]

  • Synergy Hacker - If the player also has Lower Case r, its damage is increased by 25%.
  • Synergy Square Brace - If the player also has Polaris, it gains 20% increased damage, higher ammo capacity and magazine size, faster fire rate, and a new appearance.
  • The Bracket Key can hit bosses such as Cannonbalrog and High Priest during attacks where they are normally invincible.
  • The explosion cannot travel to other rooms (e.g. using the item in a room adjacent to a chest room containing a Mimic will not damage it).
  • Unlike Big Boy, the damage done by Bracket Key will not contribute to its own recharge.

Trivia[ | ]

  • The Bracket Key's description and functionality suggests that the right bracket key on the keyboard was used during development of Enter the Gungeon to automatically clear rooms for debugging purposes.
  • The synergy Synergy Square Brace is a reference to the character Curly Brace from the game Cave Story, where the gun Polaris is also from.
