Analog Stick

Analog Stick is a passive item added in Afterbirth †.

Effects

 * +0.3 tears up
 * Allows tears to be fired diagonally.
 * With a keyboard or using buttons to fire with a controller, tears can be shot at 45-degree angles by holding two buttons. This is known as eight-directional firing.
 * With an analog controller, analog input is accepted, allowing full analog aiming in any direction.

Synergies

 * /: When tears are fired diagonally, the split tears will also move diagonally.
 * : Allows bombs to be fired in the cardinal directions and diagonally.
 * : Flames as well as tears can be fired diagonally.
 * : Explosive tears can be fired diagonally.
 * : Tear barrage and stone can be fired diagonally.
 * : Eyeball tears can be fired diagonally and can be knocked around by other tears.
 * : Lasers can be fired diagonally.
 * : Laser rings can be fired diagonally.

Interactions

 * : Allows the laser to be fired diagonally.
 * : When bone tears are fired diagonally, the bone shards will not always move diagonally.
 * : No effect because missiles already can be fired in any direction.
 * : Needles can be fired diagonally, however, burst needles will fire in all directions.
 * : When tears are fired diagonally, the split tears will burst in random directions.
 * : Incubus cannot fire in non-cardinal directions, only tears up applies.
 * : Tears can be fired diagonally and be fed. However, when they burst, they will burst in all directions.
 * : No effect because the tear can already move in any direction.
 * : Overridden by Marked.
 * - Only the tears up applies, as Mom's Knife can already be fired at 45-degree angles without Analog Stick. However, if the player is using an analog controller, then Analog Stick is helpful as it allows full 360 degree movement.
 * : Tear barrage can be fired in roughly diagonal directions.
 * : Overriden by Tiny Planet.
 * - Overriden by Tractor Beam since the beam is only in a cardinal direction.

Trivia

 * The name and item sprite is a reference to a part of controllers used for moving characters and the camera in video games.
 * The item is similar to allowing firing in more directions. For use without an analog controller, Marked fires in more angles than Analog Stick, however effective cursor control is needed.
