Lots of these might be in the game already. I don’t often get much past the scrap crowbar phase.
TL;DR: Thermite, explosive .45 shells, more CZ pistols, less silenced guns without proper ammo.
Guns:
[spoiler]
Common guns: Where I live, you can find at least one of these in pretty much any gunowning household. I live in Canada, so it’s pretty easy to assume the “you can buy nukes over the counter” world of C:DDA would also contain these, what with the more progressive gun laws and all. Most of them are old right now, let alone in the future, but they are still in very common use around here because it’s pretty hard to straight up wear a gun out. The argument that they are out of place in a world with plasma rifles holds little water with me, because I’ve noticed most people who own guns tend to hang on to the ones that work, even if they are a little obsolete.
-Lee-Enfield No. 4 Mk.1 (The longest issued bolt action rifle in existence, and if you want to count the rest of the Enfield lineage (though most are unrelated blackpowder designs), the statement could be made that these sorts of rifles are a big factor in the fact that we are speaking English right now. Still issued here and in other places in .303, though .308 models are made these days and might be more convenient ammo-wise. For the lulz, could be made as a No.1 Mk.III*, which is an older version that can attach a 16 inch (!) sword bayonet. Unlike the mosin, which is in game, these guns can be repaired using parts off other enfields of the same version without any gunsmithing)
-Cooey Model 84 (single shot shotty of various gauges, particularly useful if Molotov launchers seem like a good idea - see below)
-Cooey Model 60 (.22 bolt action that can be fixed with many parts not intended for it)
-Smith and Wesson M&P Victory Model Revolver (Couple million of these things made during the second world war. The .38 special edition, because .38 S&W is hard to find right now, let alone in the future.)
-Winchester 94AE (I’m sure this must already be in the game and I just haven’t found one yet. I mean, it’s THE .30-30)
-Winchester Model 92/1873 (I think most gun guys will tell you the '73 is the nicer gun, but a 92 is much more likely to survive the apocalypse. Game needs more pistol caliber rifles and these are built in modern calibres like .44 and .357)
- Marlin 1895 (lever guns are just so practical. .45-70 is also one of the most versatile rounds out there, and is very common)
-Kel-Tec Sub 2000 (nice little 9mm carbine that weighs nothing and folds in half for storage. Short barrel, small bullet, but nice piece for someone always on the move)
-CZ 75b (9mm, probably one of the nicest combat pistols ever built. You see lots and lots of these in the hands of pro and semi-pro shooters around here)
-Ruger GP-100 (like, the best .357 wheelgun ever made. Should be useable as a hammer when you aren’t shooting zombies, just like in real life. Little brother to the redhawk. By the way, I haven’t run into one of those yet. Is the fact that they are absurdly bulky and heavy compared to an S&W 629 reflected in game?)
-Valmet rifle (they gave these AK clones out to natives living in the farther northern areas around here at one point. They are excellent .308 rifles, and were issued to these sorts of people who hunt to survive because they are one of the few guns that still work in the winter temperatures.)
-CZ 858 (another upgraded AK that’s really common here, though less so in the U.S.)
-Colt SAA or similar 1873 clone (The cowboy revolver. Colt only made a few million (lulz), but there’s a bajillion knockoffs out there in any rimmed caliber a person could want)
-Hi-Point Carbine (ugly little guns, but supposedly the best selling carbine in the U.S. right now because they are only a couple hundred bucks, and can be found in pretty much any common pistol chambering. Can also be fixed with nothing as they are really just a giant spring. Would suggest the pistol version as well, but they’re just so ugly and uncomfortable that I have trouble believing anyone would willingly carry one, despite how tough they are.)
Uncommon Guns: A serious gun guy will probably have some of these, but they aren’t EVERYWHERE.
-Bren Gun (while a machinegun from the 1930s is not really a common thing to find in working shape, these were issued well past the time you’d expect them to be, tons were made, and lots of deactivated models that could be brought back into service with a lot of time and effort are out there. Besides, IT’S ME BREN GUN!)
-Savage Model 42 (though found in lots of different calibres, the top barrel is usually .22, bottom barrel is .410 or 20 gauge. You can fix these guns with everything from rubberbands to pen parts quite safely)
-More blackpowder stuff (sure, your fancy MP5K can spit 800 rounds a minute, but I can make ammo for one of these with things I can find laying around my house. Seems like BP would make a comeback in the apocalypse for more or less the same reasons it hung around for the last 400 years. Singleshot-ness and relatively low ft-lbs of energy can be offset by a bayonet or something)
-CZ 97 (the 1911 is a great gun. The 97 does an even better job of being a badass .45 though)
-FN FAL (either semi- or fully- auto, who cares? While the U.S. was issuing M-14s and then M-16s, literally the rest of the western world was running the FN. These are so common outside of the U.S. that despite being very illegal in most countries that issued them, they can still easily be found. Less common, but still present in the U.S.)
-Makarov pistol (like Mosins and SKS’ and AKs, this sort of Russian junk can be found everywhere)
-Browning Buckmark (the only .22 semi pistol I’ve owned that just works, period. Pretty common, at least as much as a Ruger MK III. They also make a rifle version that takes the same mags)
-Smith and Wesson model 1917 (though the gun is common, the variant that can go between shooting .45 Colt and .45 ACP is not, but would make a reasonably sensible survival gun)
-Tricked out Ruger 10/22s (I’m sure the 10/22 is already in the game. If it is, we need tricked out versions, because no one just leaves them in the wood stocks anymore. Tactical styles with flashhiders and bayonets and 100 round drums jump to mind, but there some really cool kits to make them look like everything from a tommygun to a blaster rifle. Even if it’s just flavor text, would be cool)
- Taurus Raging Judge (yeah, it’s heavy and kinda poorly built, but yet again, a gun that can chamber three calibres (.410, .45 Colt, .454 Casull) just seems somewhat practical)
- S&W 460 VTR (Yeah, it’s also almost impractically big, but something that can shoot .45 Colt, .454, and more or less rifle sized .460s is just appealing. They are also quite a bit easier to shoot than you’d expect thanks to the muzzle break)
-Kel-Tec PLR 16 (though these particular kel-tec guns are a little low quality, a .223 handgun that weighs nothing and takes AR mags is also somewhat practical)
Rare Guns: Because it’s one thing to survive the apocalypse, it’s another to do it wielding a collectable.
-Radom Pistol (because it’s about the only non-CZ gun I’ve ever owned that I’d trust through the end of civilization)
-Webley Mk. V or Enfield Revolver (guns are common, ammo is rare. Neither shoot worth anything, but the bullet is nice and big)
-Walther P38 (Nazi 9mm. Something cool about wielding megatron, and the alloy frame P1 version is actually really common)
-Mauser C96 (Imperial German 9mm. Also Han Solo’s blaster)
-MG34 (8mm machine gun. You can actually buy semi conversions off the shelf here for about $3000, though they are kinda pointless schwanzgewehers)
-BRNO pellet guns (shoot a lighter bullet at about the same speed as a standard velocity .22)
-Something chambered in .300 AAC/.300 Whisper (while these guns seem pointless for a civvy in real life, being able to go from sonic to subsonic ammo (i.e. loud to nearly noiseless) would actually be a huge advantage in the apocalypse. Especially because you can make these out of very common .223 brass)
- Magnum Research BFR (picture an 1873, only twice the size and designed to kill dinosaurs. These are common guns, but should be rare in game because they are fucking horrible to shoot and are more powerful than some of the rifles in the game already, at least in the manly .45-70 chambering. You pull the trigger and get out of the way more than anything else, at least if you don’t want to hurt your wrists)[/spoiler]
Special ammo types (and a few other things):
[spoiler]I haven’t actually seen anything like this in game so far, but it seems like the crafting system is well designed and implementation wouldn’t be impossible.
- .45 cal explosive rounds (Did you know that a small rifle primer fits almost perfectly into the end of a .45 hollowpoint? Not “explosive” explosive, but I’ve seen them wreck a chunk of ballistics gel before in a pretty horrific way)
- Wax and shot 12 ga slugs (take wax. Pour wax on shot. Seal shell. See above for results)
- .45 cal “incendiaries” (can be made easily with strike anywhere matches, those lovely .45 hollowpoints, and some water. While not nearly the fire hazard real tracers are, I could see someone burning down a dry field with these if they weren’t careful)
- .45 poison rounds (as has been proven by nutso radical groups a couple times over the years, one of the things that’s more effective than a bullet is a bullet with a hollowpoint. Filled with cyanide or what have you, capped off with wax.)
- .22 caliber pellets styled as above (those “destroyer” style pellets with the big cup on the front can be given similar treatment as a .45 HP. Would make a very versatile, quiet weapon out of an otherwise potentially useless one)
- .22 CB/Low noise (really common over the shelf ammo. .22 with a reduced load. Nothing for power outside of about 25 feet, but even out of a 5 inch barreled pistol they are really quiet)
- 12 gauge battery loads (I’m of the opinion that a battery has some pretty godawful ballistics and would never be as good as a proper shell. That said, when all you have is hulls, primers, powder, and dead batteries, it’s sure more effective than angry words)
Other things:
-Fully auto conversions (Most semi-automatics can be converted to fully automatic with a couple minutes and a file once you understand how they work. The downside to this is that semi-autos aren’t really MEANT to shoot like that, and usually wear out within a couple hundred rounds, not to mention that’s it’s highly illegal pretty much everywhere IRL. Though it’s arguably not a big advantage to do this in-game (or real life, frankly), it’s a realism thing. It’s also worth noting that this could even be an unintended side effect of poor firearms maintenance in relation to certain guns - for example, if you completely disassemble certain models of SKS and don’t put them back together the right way, or do not know how to clean them, they can occasionally “slam fire” the whole magazine off when you drop the bolt. Though the mental image of your brave survivor’s rifle accidentally discharging it’s whole mag into the shelter wall as you prepare to go out and fight some monsters is funny, delaying this until you actually pull the trigger would induce a better “oh shat” moment. I know a little bit about guns, so if there was any interest in this, I’d be happy to poke through a list of guns already in game that would either have this as an issue, or be capable of conversion. Given that the trigger happy trait sort of does this in some ways, it doesn’t seem infeasibly hard to add)
-Thermite (like the easiest thing to make ever - aluminum fillings and rust is all you need, though you can add other stuff to make a sticky paste out of it, and magnesium to make it easier to ignite. It’s harder to ignite than to construct. Would be handy for burning through walls (or really anything) with less noise than an explosive, though it wouldn’t be too useful as a weapon. You can actually make quite a few friction activated explosives using aluminum powder too, but there’s already enough boom in the game, so it’s not really worth mentioning)
-Gauss weaponry (while a portable gauss rifle is pretty much impossible to build (or at least pointlessly resource costly in the case of modern militaries who have the resources to attempt it), something more stationary that is actually capable of causing harm is surprisingly easy to build right now, and would likely be quite feasible for a very knowledgeable survivor in the future to make. Would require some very rare superconductive magnets (gold-based magnets, such as those you can use in a ball-bearing “gauss” launcher wouldn’t suffice - you’d need some heavy duty stuff here) as well as capacitors, strong non-conductive materials, a pile of wiring and some method of generation some really serious amounts of electricity, but could make for a neat anti-horde trap, what with being able to shoot through many objects at once and all. For balance (and realism, since the little bearing launchers I’ve built in the past have always had to be reset after each shot), make it a single shot affair that requires maintenance between firings).
-Beer can mortars (granted, I’ve never launched anything out of one besides beercans full of cement, but this are so simple to make it’s painful and should be adaptable to explosives. Alternatively, you can make a somewhat unsafe Molotov launcher using broomhandles, 12 gauge shells, and a single shot shotgun. If you do it right, you can throw fire around 100 yards. If you do it wrong, the Molotov breaks and f**ks your day up.)
-What can and can’t be “silenced” needs a tweak. Suppressors work by capturing the gasses that follow the bullet out of the barrel, reducing the noise. If the bullet is supersonic, then it’s still pretty much as loud as it was before because of the sonic boom. .223 seems to be an exception to this due to some sort of internal ballistics I frankly don’t completely understand, and can be made pretty quiet despite going 3100 FPS. Obviously, there is a gameplay element here, but still. I can supply of list of what should and shouldn’t be suppressable if anyone is interested.[/spoiler]
.950 JDJ actually costs something like $150 per shot right now, not including the price of renting the rifle out. The current gun also weighs something like 110 pounds and still doesn’t look at all fun to shoot (something like 250 ft-lbs of recoil AFTER counting the brake, which even out of 110 lbs gun means you have about 100 lbs put into your shoulder). Might actually be cheaper to get ammo after the world ends, because it’s made from 20mm (or 30, too late to remember) shells, which I think are in game already(?). Contrary to what the article quoted says, the BATF doesn’t actually list this as a destructive device, so if SSK is still around after the world ends, and you have god-amounts of money, they can build you one without you having to worry about whether or not the feds will kick your door down for not having a tax stamp. Couldn’t find the recipe in a skill book because J.D. likes to keep all of his cool stuff proprietary and will sue you despite the world having ended*. 2-bores are nominally bigger (as with punt guns and stuff like that), but produce significantly less muzzle energy (something like 38,000 ft-lbs, very similar to dropping a sedan on something) than that monster, just like anything outside of a proper artillery piece. So not actually more powerful, just diametrically larger. If that’s what you fellas are talking about anyway.**
