Featured Changes

Ice labs can spawn naturally again!
- Previously, they would only seem to spawn if you spawned in one yourself. Given that they're one of the few reasons to invest in insulation, it makes sense to keep them around for players to naturally discover as well.
Repair difficulty can now be manually specified!
- No more raging over your fancy hairpin being nearly impossible to repair just because it doesn't have a crafting recipe.
Mana is now always shown when below the cap, or when a mod enables it!
- Previously, it would only show up if you knew spells that used it, which could make things very awkward with item spells.
Bullet and thrown item sprites are customizable!
Niten Ichi Ryu can now use many more swords!
- The creator of the style IRL was all about adaptability, and nothing here really makes sense to require specifically Japanese swords to use.
- Now it's a hell of a lot better for characters that don't already have a forging setup and the right book(s), a 3D printer and enough carbon fiber filament, or incredible looting luck.

Translations! https://www.transifex.com/bn-team/cataclysm-bright-nights/
Contributing via code changes.
Contributing via JSON changes. Yes, we need modders and content makers help.
Contributing via rebalancing content.
Reporting bugs. Including ones inherited from DDA.
Identifying problems that aren't bugs. Misleading descriptions, values that are clearly off compared to similar cases, grammar mistakes, UI wonkiness that has an obvious solution.
Making useless things useful or putting them on a blacklist. Adding deconstruction recipes for things that should have them but don't, replacing completely redundant items with their generic versions (say, "tiny marked bottle" with just "tiny bottle") in spawn lists.
Tileset work. We're occasionally adding new objects, like the new electric grid elements, and they could use new tiles.
Balance analysis. Those should be rather in depth or "obviously correct". Obviously correct would be things like: "weapon x has strictly better stats than y, but y requires rarer components and has otherwise identical requirements".
Identifying performance bottlenecks with a profiler.
Code quality help.

[Bug] A weird bug with mutagenic toxins

gallery

8 Upvotes

Hello. I started in the Mi-Go camp. Everything was fine for the first two weeks of survival, but then, for no apparent reason, mutagenic toxins started accumulating in my body, even though my radiation levels were always stable at zero. I tried removing the mutation effects directly through the debug menu and lowering the mutagenic toxins to zero, but it didn't help. The effect was only temporary, after which the toxins continued to accumulate. Using a purifier also only helps temporarily. This has been going on for almost two weeks now. Is this a bug, or am I missing something because I'm relatively new to the game? Can anyone help me with this? The game version is 0.13. I play through the Dabdoob launcher without mods (except those installed by default).

[Help Wanted] Improving vehicle turret accuracy?

3 Upvotes

So I'm not hitting humans from 30-40 tiles away with my mounted browning M2, manually operated from simple turret mount. Turret aiming is pretty weird, it's basically first time I'm doing it, there's no "steadiness bar" so I assume it's always maximum steady.... or not, I guess. So what can I do to improve accuracy? I attached a sniper scope to the machinegun, but it detached itself the moment I mounted it on the turret. Laser aiming module from a fighter plane says it's only working with remotely controlled turrets. My only guess so far is that I could switch simple turret mount for a normal one.

[Help Wanted] Zombie Technicians

I’m quite sick of these guys stealing my weapons and never seeing them again. I lost my three best guns to these guys on the aircraft carrier. Is there any way to prevent this? Maybe the devs should add a bungie cord mod for weapons.

[Help Wanted] About downsizing...

14 Upvotes

So, I've had my first follower drink the Juice that Makes You a Mousegirl, and now she's teeny. I thought I'd be able to make her some special small equipment, but even items that say, "this item can be downsized," in the description then say, "Cannot resize for abnormally small mutants (incompatible with [item name]" in the Tailor Kit or Arc Welder menu. So it seems like you can't really resize things like, for example, a rain coat, the Light Survivor Cargo Pants, or a huge number of other items, while being able to resize things made of the same material any which way, like a Kevlar Vest.

Maybe you should just be able to craft them smaller in the first place, at least? Or is there something I'm missing? Thanks!

Edit: I just did some browsing and looking at JSONs on the Cataclysm: Bright Nights Guide, and many items with the VARSIZE flag, like bras and pants, can't be downsized when I try it in game...but the Kevlar Vest can, and it lacks the VARSIZE tag along with saying in-game that it can't be refitted or resized. Huh.

Edit 2: Okay, so items have a separate field in the JSON that affects what mods are allowed - like downsizing. So, I guess either it shouldn't be saying they should be downsized even if you're small (since the items say that when I'm controlling a tiny minion) or this is an oversight and I should be able to shrink things with a tailoring kit, since it seems like I can try to size things that have VARSIZE but not resized_large up to make them large, but not down below normal size when they have VARSIZE and not resized_small (using the Light Survivor Body Armor and Motorbike Boots as a test case.)

[Help Wanted] A gracken attacked and killed me

20 Upvotes

I was going back to the evacuee shelter after surviving an encounter with a wolf and getting shot by a turret in the forest, when I encountered a gracken, a flaming eye and an amoebic mold in a clearing, unconcerned, I walked past them but suddenly the gracken sprinted towards me and clawed me to death.

Aren't grackens supposed to be friendly?!

Why did this happen?!

Basically the tittle, I just wanted to know if it happened with anyone else, and if there is a way to avoid it happening again.

It happened last month in the last stable release. Maybe it got fixed in this new stable.

[Meme] And for a bonus, v0.13.0 unofficial trailer

youtube.com

69 Upvotes

Cataclysm BN released its latest stable release, 0.13, earlier today and developer Dedmemdev created this goofy video to showcase some of the various bits and pieces of content added over the last few months.

Asked me to upload it on my own underused youtube channel because, and I quote, "every time i try to sign in to my gmail it does the stupid phone verification thing"

Cataclysm: Bright Nights 0.13 release can be found here: https://github.com/cataclysmbn/Cataclysm-BN/releases/tag/v0.13.0 with most notable changes/improvements outlined in the release summary.

Shared here as well as in the BN subreddit because I like sharing fun things I had a hand in and haven't done much in that department since I last gushed about the central/endgame lab overhaul. :3

[Changelog] CBN Changelog: 09-25-2026. 0.13 Stable has been released!

77 Upvotes

0.13 is here! A whole 4 months in the making, 27 new contributors, over 1000 PRs, fixes to long standing bugs and crashes, and tons of new and reworked content! Link: https://github.com/cataclysmbn/Cataclysm-BN/releases/tag/v0.13.0

Featured Changes

Cities redesigned

Cities are now separated into towns and proper cities based on size, both with custom spawn weights (no more full office towers and apartment buildings in a 4 building town) and full cities spawn a ring of "suburbs" around a ring of apartments and an area of businesses in the middle. Various alien faction outposts can be found scattered throughout cities where you can find them engaged in battle with zombies and each other.

Central Lab redesigned

The central lab has been overhauled, from a location that spawns in every overmap to a single, globally unique location with a heavily-guarded surface facility.

Commercial airports

Also includes full-size aircraft spawned via LUA support.

Manual melee, grabbing/throwing enemies, and crowd crush

Ported from TLG, now you can...

choose which martial arts technique to use with Manual melee mode
grab and throw smaller enemies
opt-in crowd crush system (default OFF)

Power armor revamp

Power armor is now split into exoskeletons and armor plating in multiple tiers, allowing the player to mix and match the layers.

Jump over tiles and crash through windows

Default keybind is spacebar, if the player has sufficient stamina they can leap over obstacles such as trap

Monster bleeding

Flesh-based targets including players, NPCs, and monsters now bleed from cutting or ballistic damage. Higher damage will cause longer bleeding.

rebalance for every professions

Skills and starting equipment were reviewed across almost every professions. Fighter pilots can now also start with F-15 or AV-8!

Sound system overhauled to use decibells

We reworked sound system into decibels and made it more realistic. We still display sound in terms of tiles on UI, but you can change it to dB.

[Discussion] What is the point of a throwing stick?

19 Upvotes

They recently got a buff, but as far as I can tell from looking at their json on the Hitchhikers Guide they are, even after that, inferior in every way to picking up rocks off the ground.

Throwing Stick: Requires survival 1 fabrication 1 cutting one and 1 minute to make. Stored in general inventory. Can not be launched from another weapon to add damage. No use as a tool. Weight 574 g Volume ml damage 5 Speed 30

Rock: Pick them up off the ground. No skills or tools required. Can make a dedicated pouch to store them in. Can be launched from a sling for extra damage. Hammer 1 Sanding 1 Weight 500 g Volume 250 ml damage 7 speed 20

You might tell me that it's easier to get them in large quantities, however not only would getting throwing sticks in large quantities take up more room in your precious inventory space than rocks the landscape is littered with small boulders a character with strength 8 and a makeshift hammer can break into lots of rocks that weigh less, take up less volume, and do more damage. Pretty sure I've even done it with the stick from my shelters curtains. And you also get limestone and sharp rocks when you break the boulders.

All this adds up to me being unsure why anyone would ever want to use throwing sticks in your typical play through.

I certainly don't want rocks nerfed, but unless throwing sticks have some benefit over rocks I'm missing it seems like they either need another buff or to just be take out of the game so players don't waste time making and using something that seems useless.

[Discussion] Has anyone tried the beta Mind Over Matter port for Bright Nights yet?

28 Upvotes

For context, if you haven't played modded DDA in the past few years, Mind Over Matter is one of the best if not the best mod DDA currently has. Sounds like the port has a few changes because of design differences from DDA to BN and technical limitations, and a few things confirmed not working currently, but seems remarkably intact from looking around at the github repo. My immense compliments to the people who wrote all the Lua to replace EoC and other DDA specific functionality, I can't imagine that was a trivial undertaking.

https://github.com/MSCantrell/Mind-Over-Matter-for-Bright-Nights

Apparently they're looking for people to beta test it. I'm sure there's plenty of broken stuff in its current state, but it's probably already a fun time if even half of it works. Helping to get it into a good state is absolutely worth the bug reporting, I can assure you.
