About this game

Cataclysm: Dark Days Ahead is a turn-based survival game set in a post-apocalyptic world. 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 Dodge. 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, that want what you have…

As your game begins, you awaken with hazy memories of violence and terror from when the world suddenly unravelled around you. Now you need to explore your surroundings, and secure food, water and safety. After that, who knows? Long term survival will mean tapping abilities you haven’t used before, learning to survive in this new environment and developing new skills.


- Tilesets, sound, localization and mod support;
- Backwards compatible with desktop savegames;
- Stores game data and savegames in a publicly writeable location;
- Works with a physical keyboard or virtual keyboard & touchscreen;
- Auto-saves when the app loses focus (screen locked, switched apps etc.);
- Highly customizable touch controls and automatic in-game contextual shortcuts.


- `Swipe`: Directional movement (hold for virtual joystick);
- `Tap`: Confirm selection in menu or Pause one turn in-game (hold to Pause several turns in-game);
- `Double-tap`: Cancel/Go back;
- `Pinch`: Zoom in/out (in-game);
- `Back hardware button`: Toggle virtual keyboard (hold to toggle keyboard shortcuts).


- If your game doesn't start, crashes or hangs often try toggling "Software rendering" option in prelaunch menu;
- Default tileset is high-memory consuming; if game crashes during world creation, try changing tileset to another one (e.g. "Retrodays");
- Adjust terminal size under Settings > Options > Graphics (requires restart).
- There are multiple Android-specific options live under Settings > Options > Android;
- Keyboard shortcuts for frequently used and/or context sensitive commands appear at the bottom of the screen;
- You can remove a shortcut by flicking up on it. Hold it down to see help text;
- For the best keyboard experience, use physical keyboard or SSH-friendly virtual keyboard such as “Hacker’s Keyboard” on the Google Play store;
- If game does not react to touch commands (swipes and shortcut bar does not work), try to disable any accessibility services and apps you might have running (e.g. touch assist, autoclickers etc).

I love this game, I've loved it for a long time. But if you're reading this, chances are you've enjoyed it as well. I want to talk about a few bugs ive found when chatting with NPCs, I can't find a way to open a virtual keyboard. ive tried outside apps to help, but minimizing the game/opening another window seems to crash the game 3/5 times. this is the only major issue I've run into, other than a few crashes and bugs (dont forget to save!!) this game is amazing. Thanks for the amazing port!!!

This is a very good port. I have not seen a game of this genre ported to mobile this well. The only problem I experience is switching windows. Sometimes it'll crash the game, sometimes it won't. Switching to a different app and back seems to help. There's an option to save the game everytime the app is closed, which I recommend. You'll be using your whole keyboard for this game. It takes time getting past the learning curve but well worth it.
