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…

Gameplay

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.

System Requirements

Minimum

“I played catadda 0.B on Lego EV3 brick through ssh about a year ago. Every simple move took a noticeable fraction of a second (like 0.3-0.5 second), crafting and such was very slow as well. The specs were - 300 MhZ CPU, 64 Mb Ram (+ another 64 Mb swap on microsd flash) running ev3dev (stripped ubuntu basically), ssh over USB CDC connection.” -burgerpro

“I used to test the game on an Asus EEE 700. That’s a 900MHz mobile cpu with 500MB of ram.” -Kevin Granade

Tilesets increase the amount of RAM required dramatically. I recommend at least 1GB of ram for tilesets, and there are reports of instability due to RAM exhaustion when certain tilesets are used. (The larger the size of the individual tiles, the more RAM is used)

“I regularly test the game now on a Windows netbook with a sub 2GHz single core CPU, 1GB of ram, and no graphics acceleration.” -Kevin Granade

Graphical builds run much faster with some kind of graphics acceleration. 2GB of RAM pretty much guarantees you will never have trouble with memory shortages.
