Development History & Context

The Studio Behind the Vision

Digital Sun, a Spanish indie studio founded in 2015, has built a reputation for crafting games that blend accessibility with depth. Their debut title, Moonlighter (2018), was a charming action-RPG with shopkeeping mechanics, while The Mageseeker: A League of Legends Story (2023) showcased their ability to weave narrative into action gameplay. Cataclismo, however, represents their most ambitious project to date—a departure from their previous works in both scope and genre.

The game’s creative direction was helmed by Vicent Ramírez Luzón, who also served as the narrative and design director, ensuring a cohesive vision across all aspects of the game. Art direction fell to David Aguado Aparicio, whose work on Moonlighter had already demonstrated a knack for blending whimsy with melancholy. The team’s collective passion for RTS classics like Age of Empires II, Warcraft III: Reign of Chaos, and They Are Billions is evident in Cataclismo’s DNA, but the game’s true innovation lies in its building mechanics, inspired by the tactile joy of LEGO.

The LEGO Inspiration and Early Access Journey

The idea for Cataclismo germinated from a simple question: What if you could build a fortress brick by brick in an RTS? The team at Digital Sun wanted to capture the creativity and satisfaction of constructing something tangible, where every block placed had both aesthetic and strategic consequences. This led to a modular building system where players could mix and match over 100 different pieces, each with its own rules for stability, material properties, and structural integrity.

The game entered Steam Early Access on July 22, 2024, following a successful Kickstarter campaign in October 2023 that met its funding goal in just one week. Early Access was a crucial phase for Cataclismo, allowing the developers to refine the game’s mechanics based on player feedback. Key improvements during this period included:
– Blueprint System: Players could save and share custom fortress designs via Steam Workshop.
– Rebuild Tool: A godsend for repairing damaged structures without manually replacing every block.
– Time Anchor Mechanic: A lore-friendly save system that allowed players to rewind time to a previous state, mitigating frustration from failed defenses.
– Quality-of-Life Updates: Such as drag-and-drop recycling of blocks and improved UI navigation.

The full release on March 20, 2025, introduced a complete single-player campaign, additional game modes (Skirmish, Endless, and Sandbox), and a fully fleshed-out narrative. The transition from Early Access to 1.0 was seamless, with the final product feeling like a natural evolution rather than a rushed completion.

The Gaming Landscape at Launch

Cataclismo arrived at a time when the RTS genre was experiencing a renaissance, thanks in part to games like Manor Lords and Against the Storm, both published by Hooded Horse. However, Cataclismo stood out by focusing on defense rather than expansion, offering a more intimate and desperate experience. Its post-apocalyptic setting, inspired by Dark Souls and the works of Caspar David Friedrich, also set it apart from the medieval or fantasy tropes common in the genre.

The game’s unique blend of genres—RTS, tower defense, city builder, and survival—made it difficult to categorize but easy to appreciate. It appealed not only to strategy veterans but also to players who enjoyed creative building games like Minecraft or Fortnite Creative. This broad appeal, combined with its polished presentation, helped Cataclismo find an audience in a competitive market.

Narrative & Thematic Deep Dive

The World of Cataclismo: A Tale of Hubris and Survival

Cataclismo is set in a world ravaged by a magical catastrophe known as the Cataclismo, an event that shattered civilization and blanketed the land in a toxic mist. This mist, known simply as the Mist, transforms living beings into grotesque creatures called the Horrors—twisted amalgamations of human, animal, and something far more sinister. The last remnants of humanity have taken refuge in Ciudad Hogar (Home City), a fortress perched atop a mountain, where they cling to survival under the leadership of a mystical sect centered around the Perlas, heavenly orbs that once granted humanity prosperity.

The protagonist, Iris, is a young woman born with a Perla embedded in her chest, marking her as both a savior and an outcast. As the game’s overseer, Iris is tasked with leading expeditions into the mist-shrouded ruins of the old world, seeking answers to the Cataclismo’s origins and a way to reverse its effects. Her journey is one of discovery, not just of the world’s lost history but of her own identity.

Themes: Desperation, Creativity, and the Weight of History

Cataclismo is a game about survival, but it is also a meditation on the cyclical nature of civilization. The Horrors are not mindless monsters; they are the remnants of a once-great people, their humanity warped by the same forces that once granted them power. This duality is reflected in the game’s mechanics, where players must use the ruins of the old world—crumbling walls, broken towers—to build their defenses. The past is both a resource and a burden, a reminder of what was lost and what must be reclaimed.

The game’s narrative is delivered through a combination of 2D cinematic vignettes, environmental storytelling, and in-game dialogue. The art style of these vignettes, inspired by Romantic paintings and the works of Mike Mignola (Hellboy), evokes a sense of melancholic beauty. The voice acting, though minimal, is effective, with Iris’s soft-spoken determination serving as a counterpoint to the game’s grim setting.

Characters and Dialogue: A Story of Quiet Resolve

Iris is the emotional core of Cataclismo. Unlike the brash heroes of many RTS games, she is introspective and methodical, a scholar turned leader by necessity. Her dialogue reflects this, often pondering the ethical implications of her actions or the weight of the past. The supporting cast, including the leaders of Ciudad Hogar and the survivors she encounters on her expeditions, are similarly well-written, each with their own motivations and regrets.

The Horrors, while not capable of speech, are hauntingly expressive. Their moans and shrieks, combined with their grotesque designs, make them more than mere obstacles—they are tragic figures, victims of the same catastrophe that Iris seeks to undo. This thematic depth elevates Cataclismo beyond a simple survival game, imbuing every battle with a sense of poignant desperation.

Gameplay Mechanics & Systems

Core Gameplay Loop: Build, Defend, Repeat

Cataclismo’s gameplay is divided into two distinct phases: daytime and nighttime.

• Daytime: Players explore the map, gather resources (wood, stone, minerals), construct buildings, and train units. This phase is a blend of city-building and resource management, with a strong emphasis on preparation. The modular building system allows for near-infinite creativity, but players must also consider structural integrity—walls that are too tall or poorly supported will collapse under their own weight.
• Nighttime: The Horrors emerge from the mist, attacking in waves that grow increasingly ferocious. Players must defend their citadel using a combination of static defenses (walls, traps, cannons) and active units (archers, bomb throwers, melee troops). The physics-based destruction system means that walls can crumble spectacularly, burying friend and foe alike.

This cycle of preparation and survival creates a tense, rhythmic gameplay experience. The daytime is a time of hope and creativity, while the nighttime is a test of endurance and adaptability.

Building Mechanics: The Joy of Brick-by-Brick Construction

The heart of Cataclismo is its building system, which is both intuitive and deeply complex. Players can construct walls, towers, and other structures using individual blocks, each with its own properties:
– Stone: Sturdy and durable, ideal for tall walls but heavy and slow to build.
– Wood: Lightweight and flexible, perfect for scaffolding and temporary structures but vulnerable to fire and Horrors.
– Decorations: Banners, merlons, and other embellishments that not only enhance aesthetics but also provide gameplay buffs (e.g., increased range for archers, improved durability for walls).

The game’s physics engine ensures that every block matters. Walls must be properly supported, or they will collapse. Stairs and platforms are necessary to allow units to reach higher elevations, adding a layer of logistical challenge. The ability to pause time during construction is a godsend, allowing players to experiment without the pressure of an impending attack.

Combat and Unit Management: Strategy in the Face of Chaos

Combat in Cataclismo is a mix of automated and manual control. Units will attack nearby enemies automatically, but players can issue orders to focus fire, retreat, or reposition. Iris herself is a powerful “hero” unit, capable of casting spells that can turn the tide of battle. Her abilities, unlocked via a skill tree, include:
– Time Anchor: Rewind time to a previous state, allowing players to undo mistakes (a lore-friendly save system).
– Defensive Spells: Shields, healing, and crowd control to protect units.
– Offensive Spells: Area-of-effect attacks to thin out Horrors.

The Horrors come in a variety of types, each with unique behaviors and weaknesses:
– Basic Horrors: Fast but weak, easily dispatched by archers.
– Armored Horrors: Slow but resilient, requiring bomb throwers or cannons to take down.
– Flying Horrors: Bypass walls, forcing players to use anti-air units or traps.
– Boss Horrors: Massive, screen-filling beasts that require coordinated attacks to defeat.

The variety of enemies ensures that no two nights are the same, forcing players to adapt their strategies constantly.

Progression and Technology: Unlocking the Tools of Survival

Cataclismo features a deep tech tree that allows players to unlock new units, buildings, and abilities. Research is conducted during the daytime, using resources gathered from the map. Key technologies include:
– Advanced Walls: Reinforced stone, fire-resistant wood, and other upgrades.
– Traps: Spikes, poison cauldrons, and other defensive measures.
– Units: New troop types, such as cannoneers and elite archers.
– Iris’s Abilities: Spells and passive buffs that enhance her effectiveness in battle.

The tech tree is well-balanced, offering multiple paths to victory. Players can focus on defensive structures, offensive units, or a mix of both, depending on their playstyle.

Game Modes: Campaign, Skirmish, Endless, and Sandbox

Cataclismo offers several game modes to cater to different playstyles:
– Campaign: A narrative-driven experience following Iris’s journey, featuring handcrafted maps and story missions.
– Skirmish: Player-created or developer-designed maps with customizable difficulty and objectives.
– Endless: A procedurally generated survival mode where players must hold out against increasingly difficult waves of Horrors.
– Sandbox: A creative mode with unlimited resources, allowing players to build and experiment without pressure.

The inclusion of a map editor and Steam Workshop support ensures that Cataclismo has near-infinite replayability, with players able to share their custom maps and fortress designs with the community.

World-Building, Art & Sound

A World Shrouded in Mist and Mystery

Cataclismo’s setting is a masterclass in atmospheric world-building. The game’s post-apocalyptic landscape is rendered in a stylized, almost painterly fashion, with a color palette dominated by muted blues, grays, and blacks. The Mist, a ever-present threat, swirls ominously around the edges of the map, its tendrils creeping closer as night falls.

The ruins of the old world are scattered throughout the environment, serving as both obstacles and inspiration. Crumbling towers, broken bridges, and abandoned settlements hint at a once-great civilization, now reduced to rubble. The game’s art direction, inspired by Romantic paintings and Studio Ghibli’s whimsical melancholy, creates a sense of haunting beauty—every location feels like a lost masterpiece, waiting to be rediscovered.

Sound Design: The Symphony of Survival

The audio design in Cataclismo is understated but effective. The game’s soundtrack, composed of plucky strings and ambient hums, evokes a sense of quiet desperation. The lack of bombastic orchestral scores is a deliberate choice, reinforcing the game’s themes of isolation and resilience. The sound of blocks clicking into place during construction is oddly satisfying, while the Horrors’ guttural moans and the crunch of collapsing walls add to the tension.

Voice acting is sparse but well-executed, with Iris’s soft-spoken narration serving as a guiding light through the game’s darker moments. The absence of constant chatter from units is a refreshing change from other RTS games, allowing the player to focus on the strategic and emotional weight of each decision.
