Cataclysm: Dark Days Ahead is a post-apocalyptic zombie survival roguelike game with procedural world generation. It is heavily focused on crafting and exploration.

The game is set in near-future New England after a catastrophic event killed most of the human population and spawned various monsters and hazards.

Surviving is difficult: you have been thrown, ill-equipped, into a landscape now riddled with monstrosities of which flesh eating zombies are neither the strangest nor the deadliest.

Unlike most roguelikes, it has no goal: the player is free to explore the procedurally generated map, clear areas of monsters, work with NPCs, and build shelters and vehicles.

The gameplay is mainly based on day-to-day survival, and the game tracks parameters like hunger, thirst, morale, illness and temperature which the player must manage to stay alive.

There are several other things in the game such as NPC Quests and Secret Structures.

Cataclysm: Dark Days Ahead is heavily focused on crafting with many basic necessities such as clothing and food being craftable from raw items that are found lying around.

There are several professions and scenarios to choose from during character creation, as well as a variety of positive and negative traits.

The game also provides the player with a robust platform to construct structures and build/modify vehicles.

The game includes vehicles, bionics, mutations, realistic fire and smoke effects, real-life seasons and a wide array of combat and crafting skills.

Good but not without fault

If you like dwarf fortress, you’ll enjoy this. Think DF adventurer mode. You set parameters for your world including monster spawn rates, loot rates, nods, etc. then you creat your character, there’s a multitude of scenarios for added challenge, professions for different skills (from survivor to bionic soldier to used car salesman to clown to firefighter and more), give them traits and flaws, adjust your stats, and add points to your skills. You then spawn in the scenario of your choice and the world is your oyster. The game has an in-depth and “practical” crafting system, health system, equipment/clothing layering, vehicles, and more. Combat is relatively simple and I wish that you could be more strategic such as targeting specific areas.

The game is still in development so it’s not without its flaws. Unfortunately, it seems like the iOS version has not been in updated for years, it’s not a supported version by the creator. If you enjoy this, check out the pc/Mac version. It’s got more features and bug fixes than the iOS version.

I’ve spent weeks playing this game, it’s very punishing but risk doesn’t come without reward.

It’s a long shot

This game is great I’ve been playing nonstop the past week or 2 and it’s basically everything I’ve ever wanted in a game but what’s killing the fun is after awhile I started noticing the game crashes or just breaks for several different actions/ random encounters. These crashes weren’t an issue when I first began playing but now I can’t go 10 mins without the game crashing cause I wanted to fire a weapon. I found a fix but it’s not exactly a satisfactory, you’d have to start a new character to avoid these bugs that plagues your previous character. Now I just wanted to say i know it’s a long shot from here but I’d really like an update for the game, i know it’s been around 3 years since they last updated it so it’s likely an abandoned project but if y’all are still sticking around y’all could give us this last update that fixes several bugs I’m sure have already fixed in the web version of the game it’d be awesome. Despite the bugs, I do still enjoy the game, I’ve even recommended it to a few of my friends just have to work on these issues and the experience would be 200x better.

Beats the pants off several paid apps

I am stunned by how deep this game is. The interface seems cryptic at first but it's solid and a little practice is all it takes.

Imagine starting the game as a drunk, depressed, infected celiac barbarian in a world of pizza shop animatronics, joke monsters, energy weapons and dinosaurs. All possible, m'friend, or you can be as traditional as you like. Love how points can be spent on traits, skills, stats, and professions, and taking flaws gets you extra points. Will be buying the sound pack to support the devs! Thanks for all the effort!

Update: if you get killed in a world, you can still play another character in that world and try to build on what progress has been made in a shelter. Love the interface. Just a few tips for beginners: the comma key is your friend, butcher all you can and try to craft with it, including non-animals, and be sure to wield any weapons you have at the start.
