Oh God. Even the bullets shoot bullets.There's Abnormal Ammo for those cases when your weapons fire something unusual. But what if your weapon fires stuff... that also shoots projectiles of its own? That would be cool, right? Recursive Ammo is what happens when ammunition for a certain weapon uses another level of weapons to do the dirty work. In Real Life, the secondary ordnance is called "sub-munitions". This does not include things such as fragmentation grenades, Attack Drones, or missiles with multiple thrusters that break away. Various forms of Real Life versions of these weapons will show up anytime someone decides to look up modern weapons. Bullet Hell games in general tend to make use of this trope, as interesting patterns and changes of direction of bullets is their bread and butter. Can be one of the three different types of Spread Shot and frequently a way to instigate Splash Damage. Sub-Trope of Abnormal Ammo and Matryoshka Object.

Anime and Manga
- Code Geass has a unique Humongous Mecha in episode 8 called the Raikō that uses a massive railgun that fires shells that split into several dozen pellets, each "pellet" being roughly the size of a tennis ball.
- Earlier on, there was a one-off Knightmare weapon called a chaos mine which is thrown like a grenade but at the top of its trajectory, it opens up and releases a sustained barrage of pellets on the target from above. Euphemia almost gets killed by one but as it turns out, chaos mines are ineffective against the Lancelot's Blaze Luminous.
- Cowboy Bebop, episode "Gateway Shuffle": a group of insane ecoterrorists launches a large bomb toward a moon. As our heroes near it, it opens and releases three missiles. Two are destroyed by Spike, and just as he's about to destroy the third, it splits further into a thousand tiny rockets.
- In Dragon Ball, Krillin uses a Ki Attack variation of this where he throws an energy ball into the air which then breaks apart raining death on all those below.
- Mobile Suit Gundam SEED had various battleships and such that fired missiles into the air, which would then fire a rainfall of shrapnel to cover the enemies. It's been one of the most successful tatics for heroes and villains alike.
- Mobile Suit Gundam: The 08th MS Team has a similar weapon fielded on Zakus as anti-infantry measures. When a bunch of guerrillas charge at a downed Zaku, the pilot fires three of these into the air. Two are shot down by small arms fire but the third explodes into a brutal rain of shrapnel that shreds the entire guerrilla force in a second.
- Mobile Suit Gundam 0083: Stardust Memory has several that are mounted on the GP03 Dendrobium in the form of missiles that shoot other missiles.◊
- The Zeon Xemel mobile suit that bombarded the base in the first episode also fires cluster munitions.
- Combattler V BIGGU BURASUTO! DIBAIDAAAA!!!
- Full Metal Panic! pulled this off in The Second Raid season premier: when the Arbalest is retrieved by the Tuatha De Danaan, the sub fires several cluster missiles onto the tanks lining the riverside. The entire army gets wiped out in seconds.
- Mobile Suit Gundam 00 Ali al-Saachez's custom Enact has a rifle attachment that launches a micromissile-launching missile.
- Evac's missiles in Transformers Cybertron, opening up to release a zillion smaller missiles.
- Naruto has the Shuriken Shadow Clone Jutsu, which causes one throwing start to become a wide area cloud of them.
- Banner of the Stars has antimatter mines that, when shot at by point defences, split into even more mines. These mines disguise themselves as the debris of the destroyed mine, and then jump any Abh spaceship that strays too close.
- Transformers comic, Blustreak uses a missile like this as one of his signature weapons.
- Iron Man: The Jericho missile at the beginning splits up and proceeds to simply level a small mountain.
- The Avengers: A miniaturised version of the Jericho (from Iron Man) is shown as part of the suit's arsenal, used to take out multiple Chitauri.
- Hawkeye also uses an arrow which embeds itself in one of the Chitauri and then releases a spray of projectiles into several others.
- Star Trek The missiles of the Narada which break open and deploy warheads.
- Spawn starts with Al performing an assassination with one of these.
- Who Framed Roger Rabbit there was a cartoon gun that fired bullets modeled as western characters who then shot or otherwise killed their target with their own weaponry. Although they're pretty much the opposite of smart ammunition, demonstrated when a bunch of them hare off in the wrong direction.
- Night Watch the film Day Watch, there is an aluminum foil ball attached to a rubber band. If thrown, it unfolds in midair and splits into three identical, but faster and harder, balls, which also split, etc. It devastates Moscow in one strike.
- Hansel & Gretel: Witch Hunters. The Action Duo leave one of their anachronistic rifles with a Kid Sidekick they've picked up on the way, and he uses it to shoot at the Big Bad as she's zooming by. Cue Bullet Time shot of the bullet unraveling in mid-flight to spray pellets in a make-shift Anti-Air projectile that shoots down her Flying Broomstick.
- In David Brin's Uplift series, some of the more advanced Galactic missles have multiple layers to them. In Startide Rising, the Soro fire missiles at a Synthian scout. He fires anti-missile missiles at them, and the missiles shoot them down with Beam Spam!
- Night's Dawn Trilogy, starships launch "combat wasps", which in turn launch "submunitions".
- Honor Harrington features missiles that shoot several dozen laser beams in a shotgun-like spread, powered by a small nuclear warhead. This is based loosely on a Real Life concept; see below. Loosely speaking, the series contains spaceships that launch pods which then launch multistage missiles that are capable of spraying lasers everywhere.
- Dale Brown books since Fatal Terrain include the submunition-laden Wolverine cruise missiles. In addition, various UCAVs, although meant to resupply from a mothership and go for more attack runs, mount warheads of their own just in case.
- In Banner of the Stars, the United Mankind develop a new type of mine (other sci-fi series would probably call them torpedoes), which can divide into four independent mines to overwhelm point defense guns or lie in wait in debris fields until a ship passes by. They're dealt with by deploying More Dakka.
- In Harry Harrison's Northworld series, mention is made of shield penetrating bullets that hit a shield then fire another shot at the same now weakened spot, up to twice. note This is probably also inspired by a Real Life weapon, the explosively formed penetrator.
- In Harry Turtledove's Worldwar, cluster bombs are one of the modern-era weapons unleashed on World War II-era Earth by The Race. It takes a while for the contemporary soldiers to get used to them and several are crippled by bomblets blowing off one of their feet. Fortunately for humanity, they're also one of the weapons the Race only has a very limited supply of.
- Fyodor Berezin's novel Ash features orbital defense railguns that automatically target incoming missiles. Then we find out that there are even larger railguns that launch those smaller railguns. On the other side, many of the missiles launched from the planet are multi-stage MIRVs, releasing thousands of warheads and even more decoys. Some of the missiles are cluster bombs where each bomblet is a tiny nuke that uses californium (which has a smaller critical mass than plutonium).
Live Action TV
- Thunder LRMs are essentially missile-deployed minefields, which even come in a variety of distinct types. FASCAM (see the Real Life section below) and cluster rounds for proper artillery weapons also exist.
- Also, the Maximum Tech book introduced several types of specialized autocannon ammunition, one of which was a sub-munition round, which broke up after firing, like the special ammunition for the LB-X series of autocannons (Which were more like shotguns than autocannons.)
- GURPS: Ultra-Tech has Smart Explosively Forged Projectiles that fly over the target before using the explosive force of the warhead to create a flaming armor piercing spike.
- Star Fleet Battles drones (missiles) include multi-warhead capacity, such as Starfish drones and swordfish drones which fire a phaser at the target.
- Transhuman Space has military spacecraft launching "Autonomous Kill Vehicles" (AKVs), which are basically robot fighters with guns installed — except that they also capable of ramming if the situation justifies it, bringing them into this category.
- Warhammer 40,000 The Manticore Multiple Rocket Launcher has, as its most common armament, a rack of 4 (and only 4) Storm Eagle rockets. A Manticore may only fire one Storm Eagle per turn, and each Storm Eagle breaks into a barrage of 1-3 mini-rockets once the main Storm Eagle reaches the apex of its trajectory. Due to their temperamental nature, Manticores are sometimes distrusted by commanders, but having that kind of potential in firepower makes up for it.
- Touhou: Fairly rare, but present. More common is mobile bullet spawn points.
- Ketsui: Most of the final fight has bullets firing other bullets, or turning into other types.
- Bullet Heaven: Bullets that shoot bullets appear (first?) in the boss battle of the 10th level. The developer's response to the page quote:
I even tried making bullets that shoot bullets that shoot bullets that shoot bullets that shoot bullets, but that turned into way too many bullets and went out of control.
- Borderlands the best example are the MIRV mods for grenades, which are essentially cluster bombs. Anarchy-type submachineguns fire multiple bullets per bullet drawn from the magazine. Double Anarchy guns fire four bullets per bullet, albeit with poor accuracy. A rocket launcher called 'The Mongol' - It shoots rockets which shoot MORE ROCKETS.
- Bouncing Betty grenades, which launch themselves to chest height and then fire a radial pattern of explosives. Honorable mention to the Rain grenades, which launch up to ceiling height and then rain explosives or fire/acid/lightning downward. Due to their large blast areas and high damage potential the Recursive Grenades are often the best grenades available.
- S&S Orion: Aside from doing massive shock damage the bullets split into 3 smaller fragments upon hitting a wall.
- In Borderlands 2, the Tediore Corporation's guns are simply gun-shaped explosives that somehow shoot bullets. Instead of reloading, you simply toss the gun at your target like a grenade, and a "new" one materializes in your hands. Rocket launchers are special in that, once you've fired all the rockets it can carry, the launcher itself turns into a rocket!
- This is justified in game as they are real guns. Tediore is known for their quick reload speed and very cheaply made guns. The explosion isn't supposed to happen, so they market it as if it's supposed to do that.
- There's always the Torgue-made MIRV legendary, and it's seraphic counterpart the Bonus Package and Meteor Swarm for when the entire room has to die, it's a standard grenade that spawns up to 12 (For the Meteor Shower, Bonus package maxes out at a slightly saner 10) more grenades, which each spawn another grenade when they explode. The main downfall of this abomination is that the player tends to get caught in the murderstorm as well.
- Also by Torgue: The Unkempt Harold, a Legendary pistol whose explosive bullets split into three, then five, then seven projectiles in a straight horizontal line. Made even better when it has it's doubling prefix.
- Again by Torgue: In Tiny Tina's Assault on Dragon's Keep, SWORDSPLOSION!!!, a gun that shoots swords that blow up into three more swords. The Casual variants of Torgue's SWORDSPLOSION!!! gun shoot swords that explode into more swords that explode into MORE SWORDS.
- Hyperion even gets in on the action with the Conference Call shotgun. The pellets shot fire more pellets in a horizontal perpendicular path either at intervals or when it hits a surface or enemy.
- Another Hyperion gun that can potentially do this is the Fibber pistol. If the version generated has a particular barrel, the pistol bullet will break into nine shotgun pellets upon hitting an inert surface and ricochet in a parabolic arc. The pellets hit for the full damage of the original bullet. As the weapon card doesn't have a multiplier attatched, each of the pellets get the full damage amplification from Hyperion amp shields (including their Legendary version called "The Bee").
- Because of the shift in ammo types with this variation, a Gaige character with the Close Enough skill can have the skill activate and not lose half the damage it would normally lose. With enough stacks in her Anarchy ability, this pistol can become a Game Breaker.
- Razing Storm The Giant Spider Tank fires missiles into the air as a Last Ditch Move. The missiles start homing in, then shoot out even more homing missiles. However, it's not aiming for you- it's aiming for the mid-air platform that you're on...
- Command & Conquer makes really good use of this trope:
- Worms has clusterbombs and bananabombs. The latter is more fun. And the Sally Army. A wandering Salvation Army Action Bomb which explodes into exploding tambourines. Yes.
- Jet Force Gemini features clusterbombs that detonate on contact and scatter in 3 smaller bombs. The smaller bombs also explode on contact, but to prevent them from exploding almost instantly, they deploy umbrellas to float gently to the ground.
- Iji has Tor's attack Fractal Rockets.
- The Crusader series of games has an AR-7 rifle, which upon firing one shot fires five micro-rockets. It's like a shotgun that fires missiles.
- In the Mega Man series
- Shotgun Ice in Mega Man X will break into chunks upon hitting something.
- Similar thing happens with Freeze Cracker in Mega Man 7
- Spread Drill in Mega Man & Bass splits up into two smaller drills up to two times when you press the fire button after launching it.
- In Mega Man 8, the Arrow Shot upgrade splits into 5 bullets in a spread formation when it hits an enemy.
- Shotgun Ice in Mega Man X will break into chunks upon hitting something.
- Into the Void, an obscure 4X, has missiles that fire lasers.
- Descent has the smart missile, the earthshaker missile and the cyclone missile. The smart mine applies this trope to a stationary mine which releases Friendly Fireproof homing shots when triggered. From a gameplay physics perspective, some other Descent 3 weapons behave like this: the frag missile (which effectively releases Hyper-Destructive Bouncing Balls), the napalm rocket, and strangely enough the impact mortar (its explosion is actually caused by a second weapon spawned when the mortar's timer expires). Since Descent 3 weapons don't spawn submunitions when they impact something other than terrain, it means you can use the impact mortar on an enemy point blank without blowing yourself up.
- Ace Combat 6: Fires of Liberation's final superweapon Chandelier is a giant cannon with shells that break up into dozens of cruise missiles near the target.
- Call of Duty 4: Modern Warfare There's a cheat that when you throw a grenade (including those you picked up), it will explode into five other grenades. And if you happen to pick up that grenade and throw it...
- The bombs used in airstrikes for Modern Warfare appear to be clusterbombs based on the way the missile casings fall and the dispersion pattern as well.
- Call of Duty: Black Ops has a secondary grenade in the form of a Matryoshka doll in its version of Nazi Zombies.
- Armored Core has multi missiles. Demonstrated by 4A's opening animation.
- To be more precise: White Glint with a VOB fires off a big missile. The big missile's case breaks open and reveals and releases several smaller missiles.
- Team Fortress Classic has a grenade that explodes into even more grenades is part of the Heavy Weapons Guy's and Demoman's arsenals.
- Team Fortress 2 limits this for balance's sake—the only instance that appears in the game is the Pumpkin Bomb MIRV spell from the Helltower Scream Fortress Halloween update. The spell fires a pumpkin bomb that travels like a grenade and explodes when it lands, forming a minefield of six smaller pumpkin bombs that have to be detonated by firing on them yourself. If the enemy sees the field, the pumpkins can be easily destroyed at range, like sticky bombs. This tends to make it more useful for faster, sneakier classes than any of the heavy hitters.
- Sword of the Stars has the Multi-Warhead Missile. The sequel adds extra options such as an Honorverse-style bomb-pumped Heavy Combat Laser, a variant of the previous that fires multiple X-Ray Lasers instead, as well as a third that releases an Armour Piercing Heavy Driver shell.
- Mutilate-a-Doll 2 has Gun Gun. It shoots guns.
- In the Hunt has a green powerup gives your submarine these.
- Custom Robo has a few guns which do this. One fires a missile which breaks into five homing missiles, and another fires a spike of energy upward that splits into more, pauses, then comes down. There's a few more along the same lines.
- FreeSpace includes some bombs and missiles that'll spread either guided or unguided warheads when exploding - such as the Inferno or the Shivan Cluster Bomb. FreeSpace features Subspace Missiles too - but that's a bit different. You send a Tag'ing missile (or eventually paint the target with a laser) - which spawn plenty of missiles from subspace to crash on it.
- Don't know about the first game, but the sequel has similar weapons filed under "Bomber Supression Missile[s]" — Awesome but Impractical, as it's nearly impossible to hit any bombers with those. Suprisingly, however, they are very effective against enemy cruisers, which are too slow to escape the blasts, but low-armored enough for the missiles to do a lot of damage.
- Gunman Chronicles has grenade launcher, which, after some upgrades, may fire laser tripmines releasing a number of explosive balls on activation.
- Homeworld 2 brings us the Higaaran Torpedo Frigate, whose torpedoes travel towards a target at a certain distance before splitting into four small, but quick and agile missiles that chase down said target. The Recursive Ammo serves as as a deterrent against targets that are smaller than the Frigate itself. If the target is destroyed before all four hit, any missiles which are left will try to find another target to kill.
- Gunbound has this with the Kalsiddon. Shots are fired normally until they split apart into two or four missiles and a homing beacon. The SuperShot compounds this by having the shot split into 4 missiles and a beacon, and then each of those missiles split into two with their own beacons. All 8 shots hitting will cause extreme damage.
- Project Sylpheed enables you to shoot missiles that shoot missiles. They each lock on to their own individual target.
- Missile Command has MIRVs.
- FunOrb Arcanists have the Arcane Bomb, a grenade that releases three projectiles when it explodes.
- The Rogue Squadron games have cluster missiles on certain ships, which split into multiple projectiles when fired. Not quite as useful as a single missile until you pick up the Homing upgrade, which then allows the missiles to wipe out entire squadrons of TIE Fighters in a single shot. Later games also give the Y-Wing's bombs a cluster effect, spreading the damage over a wider area.
- Thugly from Donkey Kong Country Returns takes this Up to Eleven- he spits out a fireball, which explodes into a Spread Shot of three. One of the three then explodes into three again, then one of those explodes into another three!
- One item in Kingdom of Loathing is the Gift-a-Pult, which can fire gifts. It, itself, is a gift item, and is the best item you can launch from it. (It's also no longer obtainable.)
- Though not strictly ammunition, most of the Evil power enhancements in inFAMOUS do this. Most notably the grenades, which split apart when they launch, and the Megawatt hammer, which has six smaller balls of electricity trailing off of it.
- Half-Life 2 has an Abnormal Ammo variant — big mortar shells delivering several headcrabs who do the whole target-hunting part.
- X-COM Apocalypse has the Disruptor Multi-Bomb Launcher, which is Exactly What It Says on the Tin: it fires a single projectile that splits into four smaller bomblets. You can also Game Mod other weapons into having Recursive Ammo, in theory.
- Wing Commander Prophecy and its sequel Secret Ops has the Tracker missile, which consists of four Friend or Foe missiles mounted to a common frame, that break off after running a certain distance to allow the individual missiles to track on whatever target meets their targeting parameters.
- The Ratchet & Clank series often has such weapons in their games, which include large bouncing mines that explode into smaller ones, or guns that launch deadly discs that split into more discs upon contact.
- Crimsonland. The Splitter Gun's bullets split whenever they hit, causing mayhem on a screen. However, it's the only weapon that can kill you.
- Kommie Kong/Gorillazilla from Heavy Weapon has "Bursting Rockets", where he throws rockets that burst into six shots.
- Gods Eater Burst allows you to take this to ridiculous levels with its bullet creation system. It is entirely possible to make bullets that shoot bombs that shoot more bullets that shoot lasers and lightning.
- Star Trek: Shattered Universe, a space simulator game set in the Mirror Universe, has a Federation attack shuttle which fires torpedoes that split into six smaller torpedoes. One volley is usually enough to bring down another fighter. It is the most powerful player ship in the game.
- Star Trek Online:
- Cluster torpedoes, which fire like normal torpedoes but split into a medium sized but extremely dense (normal mines deploy 4 in an area about as big as a ship this deploys 20+ in that same area) auto armed mine field (the mines the track in to the target).
- The Bio-neural Warhead, a large tricobalt torpedo with point-defense turrets.
- The Variable Auto-Targeting Armament, the unique console of the Starfleet Avenger-class battlecruiser. VATA fires a pair of missiles whose effect and submunition vary by which cruiser command is active on the Avenger. The shield booster command causes the VATA to shoot tachyon beams that damage shields, and do an Area of Effect shield debuff when they hit. The weapon efficiency command makes it shoot quantum torpedoes and hit for pure kinetic damage. The maneuvering booster command turns both into chroniton weapons, which do damage and debuff speed and maneuvering. The Klingon Mogh-class, stats-wise a clone of the Avenger, has a similar console.
- Super Robot Wars Original Generation has the Split Missile, most famously used by Alteisen and Weissritter, which is a missile that breaks apart to reveal mini-missiles. The Shadow-Mirrors also use a version called the Matrix Missile in their Randgriths and Laz Angriffs. The Wild Falken and Vegalion have versions that are Herd Hitting Attacks.
- Tribes: Ascend has the MIRV Launcher, a large handheld mortar which fires a small shell that explodes into multiple submunitions after about a second, covering a whole area in big blue explosions of doom.
- In Escape Velocity Nova, the two most powerful Polaris capital ships mount a weapon known as the multi-torpedo. A decent salvo of these will reduce entire fleets to free hydrogen.
- The X-Universe calls them swarm missiles. They run the gamut from worthless (Cyclone missile; although it fires a single warhead at first, it will split up into several of them if it misses its target) to dangerously effective (Tornado missile, Typhoon missile) all the way up to Game Breakingly powerful (Shadow missile). The Flail Anti-Air missile used by missile frigates also possess the ability to select a new target if the existing one is destroyed; when combined with the frigates ability to simultaneously fire 16 Flails which individual split into 8 missiles a piece, things can get silly.
- Fallout 3 has the Experimental MIRV, which acts a lot like a shotgun that fires 8 mini-nukes in a single shot. It's considered Awesome but Impractical mainly because mini-nukes are a rather rare ammo type (there are less than 30 to be found in the entire game) and only Super Mutant Behemoths can survive being hit with one.
- Fallout: New Vegas DLC the"Gun Runners Arsenal is a DLC that adds many new guns and Ammo types. To make up for the lack of mini-nukes available in the base game, the DLC includes four new fun flavors of these miniature atomic bombs that you can buy, and a great new nuke catapult named "Esther" to launch them from. One of these new mini nukes, the tiny tots variant, is a mini nuke that splits up and becomes several more nukes. At range, this ammo type functions like a normal cluster bomb, pepping a wide area with several mini-mini nukes to kill a bigger region of mooks. This ammo also makes the nuke catapult a viable close range weapon as the sub munitions can be detonated at relatively close range without being harmed, so you effectively have a nuclear shot gun. To top it off the Tiny tots nuke only costs the same as a normal mini-nuke, (assuming that people actually sold normal mini nukes).
- StarTropics has the Four-star. A throwing star that goes forward and then splits into four stars that fire in all four directions.
- Postal 2's "A Week in Paradise" mod does like the Call of Duty 4 cheat mentioned above: One of the new weapons is an extremely dangerous explosive called the "Jihad Grenade". Play in Enhanced mode, and it splits into five grenades shortly after being tossed.
- Aurora lets you design missiles and add an optional payload to turn it into a MIRV missile or Mine. Said payload could also be an MIRV missile or mine, so you can get Missiles shooting Missiles shooting Mines that shoot Missiles.
- In Infinite Space, MRV and Cluster Missiles can be seen to split apart shortly after launch. They allow you to hit an entire enemy fleet with each volley instead of just one ship. Best when combined with the Formation Foe skill.
- Master of Orion 2 missiles can be upgraded with MRV warheads after additional research, though the only visible effect is increased damage, price and weight.
- G-Police has the Star missile. Upon firing it it instantly separates into eight smaller rockets that then all but Hit Scan on the target. It's less of a rocket and more of a cannon, really.
- Rage has Killburst ammo for the pistol. It's unclear exactly how they work, even with the reload animation that shows the magazine being inserted.
- The Gullwing in P.N.03 splits into smaller energy balls on impact with a target.
- The version of Dark Firaga used in Kingdom Hearts 3D launches a fireball that travels in a straight line until it nears a foe, at which point it splits into a multitude of homing fireballs that converge on the target.
- The Ryu Dragon and Tatsu Blaze dream eaters also have attacks of this nature, both being capable of launching fireballs that split into over a dozen more and scatter destruction over a huge area.
- There's also Spark Raid, which splits into rays of light, and the Balloonga spell, which conjures a massive homing water balloon that explodes on impact into six smaller, faster ones.
- In Bloons TD 5, the Bomb Tower's path 1 tier 3 upgrade shoots bombs each contain 8 more bombs.
- Angry Birds: The Blue Bird splits into three on command.
- The Naval Ops (AKA, Warship Gunner) games featured a few of these weapons, notably the cluster missile and splitting laser. They tended to be Awesome but Impractical as they split too wide between individual projectiles and fired too slowly to really provide decent saturation attacks.
- Monster Hunter: One of the ranged weapon classes (for a while the only ranged class) is the Bowgun, a hybrid gunpowder-crossbow that launches various forms of capsule-arrows containing anything from sticky bombs to shotgun shells to paintballs. Most of them exit their casings only after they've left the barrel.
- Portal: A promotional video mentions that the turrets encountered in game "fire the WHOLE bullet, that's 65% more bullet per bullet". For the sake of comedy, some of the cartridges end up discharging on impact in the video and sending the bullet and cartridge in different directions, but this never happens in-game.
- Sid Meiers Alpha Centauri: When a unit is designed, most of the weapons which can be chosen for it are a laser of some kind, and all of them can be made into artillery.
- Twisted Metal 4 had the Rain Missile, Rain 2 Missile, MIRV and Auto Lob. In typical TM 4 fashion, they all did about the same thing, and one of them (or two?) fired lasers.
- Ricochet Rabbit had several trick bullets, one of which would stop in front of the bad guy, pop open, and pull out its own gun to shoot.
- The Simpsons: In one episode, Nelson was drawing a robot with guns for arms fighting a plane made out of guns that shoots guns.
- In the original Duck Dodgers in the 24½th Century short, Marvin the Martian's "Ultimatum Responder" gun fires a bullet that fires another bullet right in Daffy Duck's face.
- Guns that shoot swords that shoot guns that shoot swords that shoot guns that...
- Darn, they got rid of it. Thank you, Internet Archive!
- Mr. Welch tried this once, only to get blocked by the GM:
2076. If I'm commissioned to build an artillery gun, they don't mean a gun that fires howitzers.
- The first widely used example was probably the shrapnel shell, which used a timed fuse to trigger a small explosive charge within that would deploy its payload of musket balls. So it was basically a giant shotgun launched from a cannon and rigged to shoot the enemy from over their heads. It was invented by Henry Shrapnel, whose name became a word we use to this day.
- The M65 280mm cannon fired a W9 shell whose explosive charge was ignited by a projectile within the shell, as seen here footage
- MIRVs, a nuclear cluster bomb.
- Cluster bombs.
- Explosively formed projectiles when launched from a rocket.
- Sensor fused weapon which is a smarter version of the cluster bomb.
- FASCAM (Field Artillery SCAtterable Mines), AKA "instant minefield", similar to the Generals reference above.
- The military once experimented with a bomb that opened up to reveal... a swarm of bats. Little kamikaze bats with little incendiary bombs strapped to them. The idea was to drop these over Japan — most Japanese buildings being mainly made of wood. By the morning bats roost on or near important buildings, then timed bombs go off. The Absurdity Ascendant part? The little incident where the bats escaped and took refuge in buildings all across the military base where they were held, followed by a flawless demonstration of the weapon's destructive potential. This actually convinced doubters that this was not in fact as stupid as it sounds: it was clearly effective enough for a single unit to devastate a moderately sized military base. The bat bomb, however, was not to be. The more expensive (and equally absurd-sounding at that time) Atomic Bomb was finished first and didn't accidentally go off on a friendly base, so the batty project quickly fell into obscurity despite having a handfull of enthusiastic supporters in the military.
- The Strategic Defence Initiative postulated a design for "Excalibur", a nuclear warhead powering a bunch of x-ray lasers, which inspired the Honor Harrington example above. It was never built as a finished weapon due to having a few problems on top of issues with SDI in general.
- In their early experiments with gunpowder, the Chinese invented a rocket that shoots smaller rockets. The large rocket was shaped like a dragon, and the smaller missiles emerged from its mouth. It probably freaked the hell out of their enemies.
- A modern example of the above is the Starstreak missile which launches three laser guided 'darts' to increase the chances of a hit.
- The traditional cluster bomb, releasing dozens or hundreds of grenade-sized submunitions, has been the subject of a 2008 limitation treaty, mainly because the high percentage of submunitions that go dud on impact like to stay around to make life miserable for quite a while. Notably, the US, China, and Russia are not signatories, and careful Loophole Abuse—fully deliberate—reveals that modern "smart" submunitions are exempt as long as they meet a number of criteria: bigger than 4kg, no more than 10 to a container, and have two self-disabling/self-destruct devices in case it doesn't hit anything. This makes sense, since the main purpose is to make sure they don't hang around like an unplanned minefield after the war's over.
- As a response to the above, even though not truly bound by it, the US Army has developed the world's largest shotgun shell under the Alternative Weapon Program. Fired from the MLRS rocket system it uses 800 tungsten rods to achieve much the same effect as a conventional cluster bomb but without the unplanned minefields. A similar bomb exists, though with a mix of steel and tungsten and it is intended to attack targets in cities such as fuel storage or chemical weapons without hurting anyone else.
- The GT-1, a glide bomb that could be dropped 20 miles away from the target at 10,000 feet. The bomb would gently glide down, and once it was just above the water, it released a Mark 13 torpedo.
- Similarly, the ASROC, an anti-submarine weapon consisting of a ship-fired missile that dropped a homing torpedo.
- An example in computer security is a Forkbomb, which is a program that simply launches another instance of itself.note The copies then launch copies, increasingly consuming the computer's resources until it eventually crashes.
- A similar attack on XML servers is known as the Billion Laughs Attack, which uses XML entities to exponentially recreate a string (usually "lol", thus the name), again consuming memory.
