What interesting sci-fi weaponry exists in your settings?

Yinrih don't use nukes, as they never bothered to weaponize them before discovering how to yeet things at significant fractions of the speed of light.

I've mentioned retribution fields before, which are force fields that absorb the kinetic energy of projectiles and then fire that energy back at the attacker. They were invented to counter...

...Quasiluminal munitions (Commonthroat gkg rDFrlmqrLPq or more often known by the military slang term gkrdfg, a clipped and reduced form of the above) are projectiles that travel at relativistic speeds and whose destructive power comes solely from their kinetic energy rather than a incendiary or nuclear payload.

Force projectors are used at shorter ranges. As the name implies they project force at a distance. As weapons you mostly see them on paw gauntlets as part of powered armor. By thrusting the palm forward a force extends outward beyond the reach of the attacker's foreleg, sort of a long-distance punch. They have scalong issues though. they convert surrounding oxygen to ozone, and can't be operated in atmosphere beyond a certain size for reasons I have yet to figure out.

Since yinrih are quadrupeds they can't practically use human guns. Modern soldiers use back mounted drone capsules that hover nearby and fire at enemies, similar to the Option power-up from Gradius. Older firearms are saddle-mounted and sit on the back and have a tail-actuated trigger.

  • Rail Guns. I know they somewhat exist IRL but they aren't a feasible long gun. I have such a Philip J. Fry type of love for them though.

  • You just made me realise my world didn't have any weapons at all in its worldbuilding! Maybe people would hit each other with sticks or something if they're angry, lol.

  • I am working on a 'realistic' sci/fi mech setting. Mechs are mostly used for uban combat and still need infantry support so they use those goofy spring shoes that have probably killed a few people by now to stay a head and clear any anti mech weapons by parkouring around the city. The legs retract when they need to go inside a building.

    Besides that though most of my weapons are pretty standard as I tend to focus on production history and why certain designs show up in certain parts of the solar system.

    Like I have one mech that is sort of the AK or MIG of the setting. It was built to be cheap and so simple that you can train someone to use it (well enough) in six months where other mechs take three years of training. Its also built with the intention of having easily replicable parts so its easy to take a part and smuggle. It was built near the end of the Lunar-Earth war to quickly replace Lunar colonies heavy loses. It didn't save them, but at the end of the war they had more mechs then any other solar nation combined which have been sold off to rebel groups all around the solar system. So in the end the Lunar colonies fucked everyone over including themselves.

    Another mech was designed by belter colonies who needed a standardized but easily customizable design to meet all the varied challenges they face in terms of industry. Theyn also though it was a good idea to use the same chassis for their weapons and so there are hundreds of 'rogue' colonies springing up they are so easy to get ahold of and modify to the point that they don't even need to be used just for urban combat.

    • I have slow, blocky mechs which are similarly used for urban or very uneven environments. They tend to be slow and used as either indirect fire support or a heavy weapon hardpoint rather than frantically running around do cool mech combat.

      My cheat is that in-universe there is a mech fighting league that is basically just WWE wrestling. Expensive mechs that can be more humanoid and have crazy paintjobs. Just like WWE the fights are staged and full of intricate nonsense storylines. The mechs fire low powered but visually impressive weapons at each other and pyrotechnic panels on the hit mechs explode spectacularly.

      I have this league in my back pocket if I ever want some crazy mech combat I can just take one of these mechs and put it in a circumstance where it fights for real.

    • I love mechs :D Yinrih, particularly the Knights of the Sun, also use mechs. They kept making powered armor bigger and bigger until you were piloting a vehicle rather than wearing a suit.

      Since mechs have five prehensile extremities to manage (four paws and a prehensile tail) they require a fair amount of training, so a hybrid between mech and conventional armored vehicle was developed called a "jumper" (Commonthroat qFbmg) that has conventional wheels but also has a degree of vertical mobility, able to jump, climb vertical surfaces, and even hover for a short period.

  • I suppose it depends on what you consider "interesting" - I tend to find relatively "conventional" sci-fi stuff like coilguns or advanced missiles, so long as they're fairly well designed! But with that in mind, let me discuss a few relatively unique ones:

    • C+ Artillery is... exactly what it sounds like. Actually predating FTL travel by a fair bit (humans... go figure), C+ artillery hurls a massive slug through a sequence of faster-than-light spacefolds, like skipping a stone off a pond. The results are utterly catastrophic: Not only does the projectile bypass armor and interceptors as it "skips", but the target is subject to the unspeakable gravitational shear forces at the event horizon of the final fold... and that's before the enormous slug at .99C slams into it. They're used for cracking fortress-stations and dreadnoughts, and thankfully have never been fired against a planet.
    • The typical infantry armor can be outfitted with the SPG-22, a 60mm, box-fed semi-automatic coilgun mortar. This system is mounted pointing vertically on the back, and is fed from a 4-round box magazine. It's most notable for the lack of need for emplacement: If necessary, the operator can kneel, the armor braces itself in place, and the mortar fires as necessary. Typically the user is actually aiming the system using an onboard firing computer, while an assistant operator keeps the weapon fed. In this way, rapid firepower can be pushed down to a platoon level.
    • The AGS-202 'Easifa' ('Storm') is a monstrous cluster munition: Weighing in at over 3,000kg, it fragments into several individually-guided petals, which in turn try to arrange themselves for maximum coverage of an area... before they in turn disperse a mix of pyrophoric incendiaries, high-explosive fragmentation, and guided armor-penetrating bomblets by the hundreds. They're meant to erase entire defensive lines, although if you can disperse one over a base, the results are equally terrifying.

  • I mentioned the Gauss rifles on a comment, but I wanna talk about my atom-gothic setting too though it's not quite sci-fi.

    During the forever war a lot of relics and items of magical origin have been seized for use on the front. Most people at this point don't have the piety/devotion/innocence/practice to use these things as they were intended, so creative engineers have found more unconventional uses for them.

    An example of this is the hilt of Næġling, said to have been slapped by Beowulf in his battle with the dragon. When impacted by anything made of electrum it amplifies that force exponentially. Built into the stock of a lee-enfield it's now the personal weapon of Winston Churchill III on the German front. With the Germans and Australians raising the dead, it let's him fashion bullets from crosses salvaged from the churches on the front.
