Cataclysm: Bright Nights is a roguelike with sci-fi elements set in a post-apocalyptic world.

While some have described it as a "zombie game", there is far more to Cataclysm than that. Struggle to survive in a harsh, persistent, procedurally generated world. Scavenge the remnants of a dead civilization for food, equipment, or, if you are lucky, a vehicle with a full tank of gas to get you the hell out of there.

Fight to defeat or escape from a wide variety of powerful monstrosities, from zombies to giant insects to killer robots and things far stranger and deadlier, and against the others like yourself, who want what you have.

Find a way to stop the Cataclysm ... or become one of its strongest monsters.

Cataclysm: Bright Nights is a fork of Cataclysm: Dark Days Ahead. see the differences from its ancestor..

While many of the dependencies that the game depends on are likely installed by default, some likely aren't installed by default on your distro.

Here are the commands for some of the most popular distro families:

• Ubuntu / Debian: sudo apt install libsdl2-image-2.0-0 libsdl2-ttf-2.0-0 libsdl2-mixer-2.0-0 libfreetype6 zip libsqlite3-0
• Fedora: sudo dnf install SDL2 SDL2_image SDL2_ttf SDL2_mixer freetype zip sqlite
• Arch: sudo pacman -S sdl2 sdl2_image sdl2_ttf sdl2_mixer zip sqlite

We do not support any launchers, none of them are maintained by any members of the development team and the vast majority of them do not keep up with our stable release cadence.

Bright Nights uses a mod registry for easier discovery of mods not shipped with the main game.

• with cmake
• with makefile: supports Linux, macOS, and BSD.
• with MSYS2
• with vcpkg

Gameplay and developing documentation is available in the doc directory in markdown format. You can also

• visit the official docs site
• build and serve the documentation locally

Yes, you can find the tutorial in the Special menu at the main menu (be aware that due to many code changes the tutorial may not function). You can also access documentation in-game via the ? key.

Press the ? key, followed by the 1 key to see the full list of key commands. Press the + key to add a key binding, select which action with the corresponding letter key a-w, and then the key you wish to assign to that action.

World on the main menu will generate a fresh world for you. Select Create World.

See where to place 3rd party mods, but replace mods/ with sounds/, this is the folder you will put it into

Find a soundpack such as the recommended one Otopack.

Unzip the zip into the noted folder

Then finally select it from the settings, and then restart the game.

If not in the List of common directories or it fails to work:

First boot up the game, select help, click 6 ( resolved game directories )

Place mods in the folder after "user mods: "

Otherwise:

For Windows users it is wherever your game folder is ( same level as the EXE ) /mods

For Android users using the non-legacy storage, the user mods folder is Documents/Cataclysm-BN/mods

For Linux users using the XDG directories (but NOT the flatpak): The user mods directory should be in ~/.local/share/cataclysm-bn/mods (~/.local/share/cataclysm-bn is the user directory in general)

For flatpak users, the user mods folder is ~/.var/app/org.cataclysmbn.CataclysmBN/data/cataclysm-bn/mods (the user directory in general is ~/.var/app/org.cataclysmbn.CataclysmBN/data/cataclysm-bn/)

Assuming you've managed your mods appropriately, the correct update process is to delete the old data folder (alongside the gfx folder if you want to be extra safe) and then overwrite the contents of the old BN folder with the new BN download. Deleting the old data folder is specifically necessary due to the fact that simply overwriting the old folder will not account for updates which delete files, as may happen with the obsoletion folder for example.

Don't delete any of the userdata folders!

Userdata folders are found by selecting help from the launch menu and clicking 6 ( resolved game directory )
