Guns

Guns are the player's primary method of attacking enemies, and can be found by opening chests, defeating bosses, purchasing them from shops, or receiving them from NPCs. The player can carry an unlimited number of guns.

All guns come in 5 "types":

• Automatic, which automatically fire bullets when holding down the shoot button and generally have large magazine sizes
• Semiautomatic, which can also fire by holding down the shoot button but generally fire faster by tapping it, and have small magazine sizes
• Charged, which need the fire button to be held for a short moment before the release of the projectile
• Beam, which are similar to Automatic, except they fire a continuous beam rather than individual bullets
• Burst, which work like Automatic or Semiautomatic, but fire multiple projectiles and consume multiple ammo in one shot

All starting guns, along with Gunther, Elimentaler, Casey, Dueling Laser, Windgunner, Betrayer's Shield with the Betrayer's Lies synergy, and the AKEY-47 with the Akey Breaky synergy have an unlimited amount of ammo, but are unable to break secret walls. All other guns have a limited amount of ammo, enabling them to break secret walls. Additionally, ammo can be replenished by finding ammo pickups.

If a gun is out of ammo, it can be thrown by holding down the fire button and deals 20 damage if it hits an enemy. This damage can be increased by the Ruby Bracelet, which will make the thrown guns explode upon contact with an enemy. Thrown guns can detect secret rooms.

Four guns do not appear in the Ammonomicon (and this list): the Prize Pistol, used in Winchester's game; the Mimic Gun, which can rarely replace any gun and must be used until the player picks up ammo or does enough damage; the High Dragunfire, found only in a special Secret Room; and the Windgunner, which can be temporarily used when Sprun transforms.

All guns, after emptying a clip, will have to reload, which takes a short time, varying with the gun. This time can be reduced, or entirely negated by the Cormorant synergy, If a gun is left unequipped for double the time of its normal reload, it will passively reload.

If the player is too close to a wall and is facing it directly, the gun will not be able to shoot. This prevents loss of ammo by accident in cases which bullets wouldn't hit any enemies by any chance.

If left on the ground, guns will be stolen by the Resourceful Rat. If the player has the Ring of the Resourceful Rat, guns can be traded for a similar-powered item, while having the Resourceful Indeed synergy removes the stealing entirely.

There are currently 243 guns in the game total, including 191 base game guns, 15 guns that were added in the update, 15 guns that were added in the update, and 22 guns that were added in update.
