DarkSwitch

Cyber Temple Games LLC developed and self-published DarkSwitch. It launched on PC via Steam and GOG on April 9, 2026, after two release date shifts from its original October 2025 target. The world is one of folk horror and creeping dread. Your civilization clings to the boughs of a massive living tree. Below, an endless deadly fog consumes everything it touches. There is no room to expand outward, so the only direction is up.

About the Game

The core tension of DarkSwitch comes from managing height as a strategic resource. Building upward opens new space, but it also exposes higher tiers to greater structural and defensive risk. Furthermore, the encroaching fog is not passive — it sends waves of threats that require active tower defense preparation alongside your city-building work. Meanwhile, the campaign weaves a multi-threaded narrative through every session. Choices you make during quests spiral into grim consequences that reshape your citizens’ future. Additionally, Akira Yamaoka’s atmospheric soundtrack gives the game the same eerie, desolate tone he brought to the Silent Hill series.

Key Features

Vertical City Building on a Living Tree: Instead of expanding across a flat map, players build upward through the branches of a colossal tree. Each tier requires careful planning for space, structural integrity, and resource flow. Moreover, over 80 unique buildings cover industrial, social, and defensive categories. As a result, every floor of the city demands a different layout strategy.
Fog Defense and Tower Defense Mechanics: The deadly fog surrounding the tree is a constant active threat. It sends waves of creatures and supernatural forces against your settlement. Therefore, defensive buildings must be woven into the city layout from the beginning. However, over-investing in defense at the expense of resource production leads to slow starvation over time.
20+ Hour Branching Campaign with Moral Choices: The single-player campaign runs over 20 hours of story-driven gameplay. It features quests, branching narratives, and high-stakes decisions at every stage. Furthermore, even small choices can spiral into grim, far-reaching consequences for the citizens. Consequently, replaying the campaign with different decisions produces meaningfully different outcomes.
Resource and Technology Management: The game tracks 11 distinct resource types covering both raw and processed goods. Additionally, players research new technologies to unlock specialized machinery and advanced buildings. However, resources are always scarce, so balancing survival, growth, and defense is a constant pressure. Meanwhile, exploration sends pioneers into the ruins of past civilizations to uncover rare materials and buried secrets.
