About Cataclismo
In Cataclismo you guide the last survivors of a shattered world, constructing fortresses from wood and stone to repel relentless waves of Horrors. Daytime is spent gathering resources and expanding your stronghold, while night brings fierce assaults that test every defensive choice.
The game blends a narrative campaign, hand‑crafted skirmish maps, and a procedurally generated challenge mode. A modular building system and real‑time unit command let you shape both architecture and tactics, adapting each night’s attack across varied biomes.
01 / THE GUIDE
Modular Building System
Cataclismo offers a highly modular construction system where each piece is placed individually, allowing players to design fortresses with full freedom. You can use wood for quick builds or quarry stone for durability, and must watch structural integrity as collapsing pieces can harm both sides.
Blueprints can be pre‑designed or shared via the community, and structures can grant access to new map areas or block Horrors. Natural chokepoints, height advantages, and local resources can be incorporated to strengthen defenses.
- Experiment with wood for early expansion, then transition to stone as threats increase.
- Use community blueprints as a starting point for complex designs.

Resource Gathering and Outposts
During daylight you explore the world to secure vital resources needed for construction and military growth. Outposts, recruitment centers, and citizen housing all support your troops, and well‑placed structures streamline the path from deposits to warehouses.
Rooftop construction maximizes limited space, while resource‑rich biomes can be leveraged for faster expansion. Managing wood versus stone supplies influences how quickly you can reinforce walls before nightfall.
- Prioritize building warehouses near abundant resource nodes.
- Balance wood and stone to keep both speed and durability in check.

Real‑Time Unit Command
You command a variety of units—from bowmen with sharp eyes to cannoneers with explosives—positioning them to exploit special traits and abilities as they upgrade. Troops can be placed on heights, in chokepoints, or behind traps to maximize effectiveness.
New Horrors appear over time, requiring you to adapt tactics each night. Precise positioning lets you draw enemies into lethal zones, and secondary defenses like citizen homes can serve as fallback layers if walls fail.
- Place ranged units on elevated platforms for better line of sight.
- Use citizen homes as a last‑ditch barrier when primary walls are breached.

Campaign, Skirmish, and Challenge Modes
Cataclismo includes an epic single‑player narrative campaign, a skirmish mode with hand‑crafted maps, and an endlessly replayable challenge mode featuring procedurally generated maps and escalating waves. Each mode tests your building and combat skills under different conditions.
The map editor lets you design and share skirmish maps, while the construction tools enable sharing of blueprints. These community features extend replayability beyond the core modes.
- Try the challenge mode to practice against increasingly difficult waves.
- Create custom skirmish maps to experiment with unconventional layouts.

Steam Integration and Accessibility
The game runs on Windows via Steam, supporting achievements, trading cards, and the Steam Workshop for sharing maps and blueprints. Accessibility options include camera comfort, color alternatives, custom volume controls, adjustable difficulty, mouse‑only input, and subtitle choices.
Steam Cloud saves progress, and Family Sharing is also supported. These features ensure a flexible experience across different player needs.
- Enable subtitle options if you prefer reading dialogue during night assaults.
- Adjust difficulty to match your comfort level with wave intensity.
