In Save the World there are six different types of Ammunition, all of which are. These can all be crafted, or obtained from the map in various ways.


 * is used mainly for Pistols and Submachine Guns, but is also used for some Assault Weapons. Out of the ammo types, the player can hold the most of this (max. 6000), and typically it does the least damage per shot.


 * is used mainly for Assault Weapons, but is used for some Sniper Rifles, Pistols and Submachine Guns. The player can hold plenty of it (max. 4000), but not as much as Light Ammo. As per its name, it deals a medium amount of damage per shot.


 * is used mainly for Sniper Rifles, including Bows, however some pistols use it too. Not too much of it can be held (max. 1000), but per shot it does the a high amount of damage compared to other ammo types.


 * are used mainly for Shotguns, but it is also used by the Boom Bow. They are unique in that many weapons using them fire a short ranged 'buckshot' spread, rather than a single bullet. A decent amount of Shells can be held by the player (max. 1200). The damage for this ammo type varies, but on average it deals high damage up close, and very low at range.


 * is used for a variety of weapons. A decent amount of Energy Ammo can be held by the player. Energy ammo is expensive to craft, but the weapons that use it often have unique abilities or deal high amounts of damage. The player can hold quite a lot (max. 3000), but many weapons consume multiple ammo per shot.


 * is used for Launchers. It is often a slow moving projectile which deals high splash damage upon impact. The player can hold very few rockets (max. 150), and they are not cheap to craft.

Obtained
Ammo is obtained primarily by Ammo Boxes, which supply only ammo, or in the case of the higher tier box, Small and Regular Shield potions. Ammo is also obtained from Floor Loot, in Chests, from Fishing, in Supply Llamas and in Supply Drops. Some AIs will also drop Ammo, as well as eliminated players in Team Rumble (All players drop ammo regardless of mode, but players in Team Rumble generate it upon elimination).

Trivia

 * Despite not having a pickup, has an icon like the other ammo types.
 * is referred to as Shells 'n Slugs in Save the World. This title is more fitting for that mode, as some Shotguns do not fire a buckshot, but rather a slug.
 * has appeared as a pickup in Battle Royale, appearing alongside the Zapotron before its removal.
 * is the first Ammo type to be fully vaulted (outside of Team Rumble) in core modes since its initial inclusion.

Visuals

 * is based of the 5.56 x 45mm NATO caliber rounds. These bullets are often used for Assault Rifles and Carbines in real life.
 * This is not certain however, as Medium Ammo has a vague resemblance to these rounds, but no round looks identical to the one in game. However, based on its usage in many Assault Weapons, it is fair assumption is based on the 5.56mm.
 * It is unrealistic for any pistols in game to use these specific rounds. Although something like the Revolver uses a heavier hitting caliber round than a standard 9mm round, it would not use the same as a Assault Weapon. This is obviously implemented for balance reasons.
 * is based upon 9x19mm Parabellum Rounds. These bullets are often used for Pistols and Submachine Guns. The Tactical Assault Rifle has a thinner magazine, and its use of Light Ammo is realistic.
 * In Real Life, the Minigun would use a larger caliber bullet, but for gameplay purposes and to balance the damage, it fires light ammo.
 * is based upon .338 Lapua Magnum rounds. This is true to the caliber of many Sniper Rifles, such as the Bolt-Action Sniper Rifle's real life counterpart, the AWM, which fires this round.
 * However, a weapon like the Desert Eagle (Hand Cannon) uses similar ammunition as the Revolver (.357 vs .44 Magnum), and as such should not use . This is changed in game for balance reasons however.
 * are based off 12 Gauge Shotgun Shells. Weapons such as the SPAS-12 ( High Tier Pump Shotgun) fire these rounds.
 * is a collection of warheads for an RPG-7.
 * Almost all Explosive Weapons in Battle Royale should not accept this ammunition. For most Launchers, such as the High Tier Rocket Launcher or Quad Launcher, it would be incompatible.
 * Furthermore, the Grenade Launcher and Proximity Grenade Launcher do not even shoot rockets. These changes have all been made for balance reasons.
