In plain English

Cataclysm: Dark Days Ahead is a free, open-source turn-based survival game set in a post-apocalyptic world. The game drops you into a procedurally generated world where civilization has collapsed, and you have to find food, supplies, and shelter while dealing with zombies, giant insects, killer robots, and other threats. The world persists between play sessions, so choices you make have lasting consequences. The game has two visual modes: a tiles version with graphical sprites and an older text-based terminal version using characters to represent everything on screen. Both run on Windows, macOS, and Linux. Pre-built downloads are available on the official website and through several Linux package managers including Arch Linux, Fedora, Debian/Ubuntu, and Flatpak. If you want to build from source instead of downloading a release, the repository includes detailed compilation guides for Linux, macOS, Windows with MSYS2, Windows with Visual Studio, and a CMake path. The codebase is written in C++ and has been in active development for many years, with over 1000 contributors. The project is community-driven and releases both stable builds and more frequent experimental builds with the latest changes. Contributing is welcome: code, game content, translations, and bug reports all go through the GitHub repository. The license is Creative Commons Attribution ShareAlike 3.0, which means the game and all its content can be freely used and modified. An in-game tutorial is available from the main menu, and pressing the question mark key during play opens a help reference with all key bindings.
