气球枪

• Get Equipped With -A- - If the player has [洛克手炮] , enables Air Shooter mode on [洛克手炮] , which fires Balloon Gun tornadoes while uncharged. Modes can be switched by reloading the [洛克手炮] with a full magazine.
• Paper Lanterns - If the player also has [折纸枪] , while holding either gun in a room with enemies, paper lanterns periodically spawn, which drift towards enemies and deal damage.
• Three Sheets - If the player also has [海盗船] , movement speed is increased, the damage of both guns is doubled, and their bullets travel 20% faster.
• While popped (empty due to taking damage while held), the Balloon Gun has no sprite, effectively making it invisible. If the Balloon Gun is emptied by using up its ammo reserve instead of taking damage, the gun remains un-popped and can be dropped and retrieved like any other.
• If the player drops (not throws) the Balloon Gun on the ground while it is popped, its lack of sprite makes retrieving it difficult, but not impossible.
• However, if the player throws the Balloon Gun while it is popped, the gun will disappear, making retrieving it impossible.
• Despite appearing invisible, the Balloon Gun can be sold to the Sell Creep while it is popped.
• Munchers will not accept a popped Balloon Gun, only one (partially) filled with ammo. Refilling the gun with ammo allows the player to feed the Balloon Gun to a Muncher.
• Cannot be used with [胶带] while popped.
• The Resourceful Rat can steal the item even when thrown.
• If the player has [螺旋子弹] , the tornadoes fired by Balloon Gun will never lose momentum.
• If the player has [愤怒的小子弹] , tornadoes that hit an enemy will spawn a copy every time they hit and the process is repeated indefinitely, as long as the tornadoes do not lose the lock on the enemy, leading to very high ammo efficiency.
• Since the Balloon Gun pops when the player is hit, rather than when the player is damaged, armor will not protect it. However, [全金属外衣] will protect it, due to its complete prevention of damage provided the player has blanks.
• [剩杯] , if used properly, can refill ammo for Balloon Gun. If Balloon Gun is picked up before [剩杯] , its ammo can be refilled to half-full upon taking damage. However, if [剩杯] is picked up first, Balloon Gun will break and ammo will not be refilled. This can be avoided by simply dropping [剩杯] and picking it up again.
• [火箭驱动的子弹] are a good choice with this weapon, as it increases the tornadoes' starting speed and allows them to travel farther.

• Since the popped sprite is invisible, if the player dies while the Balloon Gun is popped, it will appear to not be shown in their list of owned items on the end screen.
• Dropping a popped (empty) Balloon Gun shows a weapon icon on the map, but throwing a popped Balloon Gun doesn't, indicating that throwing a popped Balloon Gun really makes it disappear.
• The quote "Hot Air" is a reference to Hot Air balloons, given that the gun allows you to fly while held.
