* At least one expansion splatbook for MutantsAndMasterminds / True20 list ammo as Pistol 1-3, Longarm 1-3, and so on, with higher numbers corresponding to higher calibers. So Pistol 1 ammo fits holdout pistols (Derringers), while Pistol 3 ammo would be chambered by heavy pistols like the Desert Eagle.

** ''VideoGame/ResidentEvil4'': Ammo, for the most part, is totally interchangeable within any weapon of a certain classification. This leads to the 5.7x28mm Five-seven firing 9x19mm Parabellum, and the .30-06 Springfield and 5.56x45mm [=SL8=] sharing ammo (though the inventory screen flat-out states the Springfield is firing .223, so it could have been converted).
*** Furthermore, the magazines are the same size for each gun, but the ammo cap for each gun can be upgraded. Is Leon putting two mags in on top of each other?

** As mentioned in the opening of the page, NATO's draft standardization agreement 4179 decreed that all NATO weapons chambered for 5.56x45mm were to be designed to take the same magazines as the American M16. Note though that this agreement was never actually ratified; most of the armies who do use weapons with STANAG magazines tend to just use either the Canadian C7 and C8, or more rarely something with magazines that are nearly-identical to and almost 100% interchangeable with STANAG ones, like Fabrique Nationale's FNC and its derivatives. Some NATO members like France and Germany do make STANAG-compliant versions of, or adapters for, their standard-issue weapons, but they're far more commonly used with proprietary ones. The French also use a different pattern of rifling to the rest of NATO, probably at least partly out of sheer contrariness; the FAMAS can chamber and fire NATO-standard 5.56mm rounds, but unless it's the G2 variant it will have horribly degraded accuracy and range (equivalent to that of a modern 9mm pistol).

* In the game version of ''VideoGame/TheWorldIsNotEnough'' ammo types are, for the most part, identified by caliber, and are only shared by weapons that share them in real life (ignoring the OneBulletClips issues that result). However, this still results in the AKS-47 inexplicably loading the same ammo as the 7.62mm NATO sniper rifles.

** Played straight with the "Scavenger" perk - every casualty will drop a backpack with one full magazine for whatever guns you're carrying, another piece of your primary equipment, and one special grenade.

** Played Multiplayer in later games would occasionally go back to ridiculously strict requirements to pick up ammo from another gun on the ground, but games since ''Modern Warfare 2'' also allow this to be played straight with the "Scavenger" perk - every casualty (except those killed by explosive weapons in later games) will drop a backpack with one full magazine for whatever guns you're carrying, another piece of your primary equipment, and one special grenade.

* The primary and secondary weapons of ''VideoGame/{{PAYDAY 2}}'' use separate ammunition pools, but ammunition pickups restore ammo for almost all weapons (though different weapons and ammo types replenish at different rates; a box of ammo from a dead street cop will probably give you three or five bullets for your assault rifle, but only one or two extra shells for your secondary shotgun, possibly not even that if loading it with slugs or explosive shells). An attempt at justification can be seen in the ammo pickups having multiple ammunition boxes clustered together, but that does not explain why a player who only needs shotgun ammunition somehow makes all of the handgun ammo from a pickup vanish, or why exactly a policeman only armed with a single pistol are carrying five different types of ammo. Nor does it explain how a player filling up on saw blades from an ammo bag, which ''looks'' to be filled only with magazines for specific assault rifles, somehow reduces the amount of .50 BMG ammunition available for a Thanatos-equipped player.

** Due to a [[GoodBadBugs bug]] in ''Fallout 2'', the P90 {{expy}} gun was originally loaded with 9mm ammo, which was extremely rare and only (designed) to be used in this one gun (it wasn't even the only specialized 9mm ammo, either - elsewhere in the game is a Mauser that takes 9mm (ball) ammo). However, once emptied, it then took extremely common 10mm ammo.

** This was also what led to the development of the American M14 and German G3 in the 50's. NATO had standardized the 7.62x51mm round at that time and were pressuring everyone to adopt rifles of that caliber. America, owing to nationalism and wishing to make their own weapons instead of buying from another country, created the M14 based on their earlier M1 Garand rather than adopt the FAL nearly everyone else was fawning over. West Germany, meanwhile, initially ''wanted'' to adopt the FAL, but FN wasn't willing to grant them a license to produce it, owing to the fact that Germany [[UsefulNotes/WorldWarII steamrolled over FN's home country of Belgium]]. [[UsefulNotes/WorldWarI Twice, at that]]. As a result, the Germans turned to a design based on a Spanish rifle of the same caliber that their border guards were very approving of.

** In the various sequels (''VideoGame/FarCry2'', ''[[VideoGame/FarCry3 3]]'', ''[[VideoGame/FarCry3BloodDragon Blood Dragon]]'' and ''[[VideoGame/FarCry4 4]]''), all weapons of the same type (with distinctions for which slot they go in for ''2'') use the same ammunition and can get more by walking over any other weapon of its type dropped by dead enemies. This means, for example, as of ''Far Cry 4'' the pistols are all simultaneously chambered in .45 ACP, both 9mm Makarov and Para, .44 Magnum, 7.63mm Mauser, .455 Webley, and .50 Action Express. They apparently tried to justify this for the automatic rifles in ''Far Cry 2'', where they all use 7.62mm bullets in real life (even going out of their way to include an obscure 7.62mm predecessor to the AR-18 rather than any form of M16), but they ignored the fact that the AK-47 doesn't use the same 7.62 bullets as the others; conversely, this also means that the player can be carrying two 40mm grenade launchers or 12-gauge shotguns and ''not'' share ammo between them for no other reason than because one of them is being used in place of a pistol and the other in place of a rifle.

AcceptableBreakFromReality. This trope is similar to OneBulletClips since both of them treat ammunition like water that's just decanted into a container of the right type when needed; here the container in question and its contents can magically change depending on what it is being attached to, whereas there it's more about the way every magazine not being held is immersed in the ammo-liquid until it is as full as possible.

Before adding examples please keep in mind that a lot of weapons from video games are based on real-life weapons. Many military and civilian weapons very intentionally use common "standard" ammunition sizes and magazine types (like the NATO 5.56 and 7.62 rounds for assault and battle rifles). Most 5.56mm weapons use the magwell dimensions specified under the draft STANAG 4179, meaning one can take a magazine from any such weapon and use it in another. However, if the magazine is interchangeable but visibly different depending on the weapon (for example, a steel 30-round magazine for an M4 turning into a polymer PMAG when it's put in an [=HK416=]) it is still this trope. If two weapons that have interchangeable ammunition in real life use ''different'' ammunition in the game, it is an [[InvertedTrope inverted example]].

"Compatible magazines" is an important distinction: if a Luger, [=MP40=], [=MP5=] and Glock 17 all share a "9mm ammo" pickup, there's still behind-the-scenes magic going on. Let's say you pick up a 32-round [=MP40=] magazine under the above. You can use it to reload the 8-round Luger, the 17-round Glock, and the 30-round [=MP5=]. This could only really work if you picked up the [=MP40=] magazine itself along with four empty Luger mags, 2 empty Glock mags, and 2 empty [=MP5=] mags. Obviously, you didn't just pick up nine magazines, eight of them empty, so instead of having magic transforming bullets you have a magic transforming magazine.

Note that most EnergyWeapons batteries/power sources, in contrast to the panoply of batteries in RealLife, are portrayed as universal. Just pop in a random battery and they're good to go.



Can also be a JustifiedTrope in modern shooters, as many military and civilian weapons very intentionally use common "standard" ammunition sizes (like the NATO 5.56 and 7.62 rounds for assault rifles) or certain calibers of ammunition tend to be overwhelmingly popular for certain guns (the .40 S&W and 9mm Luger loads for pistols), and the ranges at which video game firefights usually occur are in real terms absurdly short ("sniping" at 50 meters or less is a common "long range" option), making the difference in propellant loads rather moot due to basically everything flying completely flat at 5 or 10 meters (a typical range for everything that's not "sniping").

Note that most EnergyWeapons batteries/power sources, in contrast to the panoply of batteries in RealLife, are portrayed as universal. Just pop in a random battery and they're good to go.

Before adding examples please keep in mind that a lot of weapons from video games are based on real-life weapons. When two weapons which use compatible magazines in real life use the same ammunition in a game it is not an example-- though if those two weapons use ''different'' ammunition in the game, it is an [[AvertedTrope averted example]].

[[labelnote:note]]There are M1911 clones that are chambered for 9x19, but the one in the game has a magazine limit of 7 rounds which is the limit for .45 ACP.

The Glock 17 caps off at 10 rounds when it should hold 17; 10 round mags for it exist but they are only for civilians in [[UsefulNotes/AmericanGunPolitics states with magazine capacity limits]], of which Louisiana, where the game occurs, is not one. The Makarov is capped at 9 rounds when the real magazine sizes are either 8, 10, or 12. It would be 9 if there was a +1 in the chamber, but the other two guns don't follow this convention.[[/labelnote]]

** Averted to a slightly unrealistic degree at times in the earlier games. Even the normal and sniper versions of a weapon did not have interchangeable ammunition; while in some cases like most bolt-action rifles this was at least semi-accurate since attaching a scope made it impossible to reload them using stripper clips, it was even the case when the weapons ''should'' have used exactly the same ammunition loaded exactly the same way, like the Sten being nearly-impossible to replenish despite taking the same magazines as the [=MP40=]s every other German soldier drops, or a scoped Mosin-Nagant [[GoodBadBugs reloading with clips anyway]] but not being able to take more from unscoped ones.

* ''VideoGame/DeusExInvisibleWar'' takes this trope to the extreme. Anything that uses ammunition uses ''the same ammunition'' as everything else. The in-game explanation is that ammunition is reduced to a slurry of nanomachines that form into the proper ammunition for the weapon. This includes battery packs, flame thrower fuel, regular bullets, and even '''rockets'''. The creative reason behind this is that the inventory system got simplified, and [[AcceptableBreaksFromReality carrying 20 types of ammo didn't sound appealing when you only had 7 spaces]]. This has the major drawback of burning your ammo with one gun means you're screwed.
** Averted in the first game, and wasn't an issue because ammo was stored in a HyperspaceArsenal ([[BadassLongcoat your coat]]) separate from the normal GridInventory. That said, pistol and sniper ammo were simply cartons of loose bullets rather than magazines. That's OneBulletClips for you.
