About this gameFull description from Steam
An apocalyptic cataclysm has happened… more precisely, all of them did, all at once. Within the last few years, riots and wars shook the Earth, devastating its population, and finally, the grid has completely collapsed. As if that weren't enough, there are zombies?! Evil mushrooms!? Giant hornets?! You'll need to make the best of things and figure out a way to survive. In this expansive survival RPG, you'll have to find or craft tools, kill monsters, gather allies, build your home base, grow crops, and survive a world that grows ever harsher around you. Find a working vehicle and use that to explore the wasteland of New England! Who was the mysterious "XEDRA" that left artifacts around the dying world, and how are they connected to the cataclysm? Cataclysm: Dark Days Ahead is the epitome of a modern roguelike: with turn-based play and a RPG-like skill progression system, it hearkens back to the classics of the genre while building on them in unexpected ways. The depth of this game will surprise you, with a cleverly-designed inventory system, the ability to drive vehicles on land or water, well-written NPCs with their individual stories, and more. The scope of Cataclysm is unparalleled in the genre, thanks to a dedicated community that works to create this game collaboratively, as we have for over ten years. Complex and diverse enemies from ever-mutating legions of the undead, to giant insects, to existential horrors from between worlds. Unparalleled vehicle building and customization system. Immersive, exquisitely detailed crafting system covering everything from smithing and soldering to keeping your sourdough starter fed. Build almost anything you can imagine, from a wattle-and-daub shelter in the woods to a tower of reinforced concrete and living alien resin. Populate your base with NPC allies that help you craft and keep you company. Explore one of the most detailed and immersive skill and proficiency systems in any RPG. Ever expanding content, with new major updates released regularly. Challenging, rewarding game balance that forces you to evaluate every step, or pay the price. You'll soon see why most of the world's population is dead! …want to feel like you might actually be able to survive against an incredibly harsh and unforgiving apocalypse. …have ever wandered through a hardware store thinking "This would be a great place to hole up when the zombies come." …love survival RPGs but get frustrated when you can't hotwire one of the nearby broken-down cars, weld a makeshift ram to the front, and plow it through the gates of the next story-important area. …enjoy detailed simulation-style games, but also want to mutate into a bizarre cat-girl slime mold creature with a cybernetic gun arm in one. What do you get for purchasing the Steam Edition of CDDA? Steam cloud support for save games. Graphical achievements. A chance to help the CleverRaven team in supporting one of our long-term developers, working on one of the best open-source games on the internet. More planned… check back soon!

  1. 0.I (Ito) has come to Steam!

    It has been a rocky few months for me, but I have finally made some changes in my own life for the better, and have found my way back to developing. I apologize for the delay; the stable itself took a long while, and my own updates also…

  1. Fix - add sounds back

    The update deleted CC-sounds, so I added it again from the public repo. If you started the game without it, it would have reverted, and you'll need to go to the options menu and select CC-sounds again.

    Patch notes
  2. Workshop is live!

    You can now upload and download mods via Steam Workshop! I made it as simple as possible - you create a mod that the game can see as a mod (see the documentation on creating mods on the repo) and you press "Upload"! It's as simple as that!…

  1. Disable Cloud Config

    There are some issues with having configs saved in the cloud, such as not being able to delete and reset them easily, and also if someone has multiple platforms they play on with different keybindings. For that reason, the cloud no longer…
