|A standard baseball bat, modified to hit bullets instead of balls. Launches enemy projectiles back with a vengeance!
Casey is a melee weapon that increases curse by 2. Swinging the bat after a long charge-up will damage nearby enemies and reflect nearby bullets. The bodies of enemies killed by the bat's tip will be launched and can damage other enemies: the damage dealt by launched bodies is equal to double the launched enemy's max health.
- Careful Iteration - If the player has Armor of Thorns, Shotgun Full of Hate, Nail Gun, or Eyepatch, Casey becomes spiked and fires a spread of 6 nails each time it is swung. When an enemy is hit with Casey, they will become dark red and take damage over time.
- This also changes the sound effect of "readying" Casey. This change also seems to be affected by Scattershot causing the new sound effect to multiply.
- Casey's swing actually fires an invisible short-ranged projectile. This projectile can be made visible with modifiers such as Cursed Bullets, and can even be spawned by certain items, such as Hip Holster or Orbital Bullets.
- Casey bullets spawned this way do not reflect enemy bullets, however.
- Reflected bullets are affected by the player's bullet modifiers - Homing Bullets will give deflected bullets a chance to home in on enemies, Shock Rounds will cause deflected bullets to become electrified, and so on.
- Ghost Bullets are an exception to this, as reflected bullets do not pierce through enemies.
- If combined with Flak Bullets, Casey will shoot three high damage pellets, making Casey more functional as a long range weapon. These bullets also retain Casey's "launch upon death" property.
- Casey can deflect the High Dragun's rocket attack, but the deflected rocket will not deal damage.
- Most explosive enemies killed with Casey will have their explosion delayed to prevent unnecessary damage taken.
- This doesn't apply to things like explosive barrels or Challenge Mode's "Explosive Pyre" modifier.
- The Laser Sight will not appear when holding Casey.
- The swing from the bat can reflect the bullet portals summoned by Killithid.
- If the Bullet King or Old King’s Chancellor is launched into a boss, the Chancellor’s body will deal a large amount of damage to the boss it hits, killing both Bullet King and Old King in one hit.
- This does not work if the chancellor is jammed.
- This weapon is a reference to the poem Casey at the Bat, written in 1888 by Ernest Thayer.
- This might also be a reference to Casey Jones, a character in the Teenage Mutant Ninja Turtles known for fighting with various sporting goods, such as hockey sticks and of course, baseball bats.
- This gun is among those Gunsling King and Manservantes can challenge the player to clear a room with.
- The top half of the bat is a shotgun shell casing, making its name a pun.
- The quote "Nothing can happen until you swing the bat." is from FLCL.
- The tagline “Batting .50” is a reference to .50 caliber bullets and Batting Average in baseball (a theoretical 0.500 being impossibly good).
- The fact that the weapon increases curse while being carried stems from the Gungeon rejecting melee weapons.
- Usually, opening a chest containing Casey causes it to appear on the right side of the chest, instead of the center.
- Whenever the player finishes a round with a super punch in the Resourceful Rat's Punch-Out!! phase, he will swing Casey at the player. Even if the player has Casey, The Rat will still use it and the player will be unable to.
