KLETKA, the 6-player co-op horror roguelike set inside a cannibalistic elevator, just got a massive update on November 3, 2025. Version 0.4.0 introduces the Greenhouse Unit biome as the primary new location, complete with unique enemies, drivable vehicles, cross-platform leaderboards, and a haunting narrative twist involving infected crops and spores. The Greenhouse Unit represents the agricultural heart of the Gigastructure, once humanity’s food source, now corrupted by hogweed spores that animate machinery and corrupt living organisms alike. This update takes KLETKA’s existing roguelike formula and expands it dramatically.

The Greenhouse Unit Biome Arrives With Narrative Weight
The Greenhouse Unit isn’t just another random procedural biome. It’s deeply tied to KLETKA’s worldbuilding. According to the patch notes, the Greenhouse Unit was once the agricultural heart of the entire Gigastructure. Humanity designed it to provide sustenance for everyone. But those “best years are long gone,” and humanity has been replaced by Samosbor and its descendants. The Greenhouse fell into ruin, and the crops became infected with hogweed spores—which are “highly dangerous things.”
When spores infiltrate machinery, they form organic networks and emit electric impulses that animate mechanisms. Imagine what happens when those spores enter living organisms. This premise creates genuine horror: not just monsters, but the corruption of something meant to nurture life. It’s body-horror meets agricultural collapse. The Greenhouse Unit will spawn as the second biome in both Heart of Gigastructure and Turbostruct modes with a 90% spawn chance, meaning players will encounter it frequently.
Drivable Vehicles Change How Exploration Works
One of the most significant additions is drivable vehicles. KLETKA has been a first-person descent through increasingly dangerous floors. Adding vehicles transforms level design possibilities dramatically. Vehicles let players cover ground faster, navigate hazards differently, and potentially tank damage in ways individual players couldn’t. This fundamentally changes combat and exploration strategies.
While exact vehicle mechanics haven’t been detailed publicly, the inclusion of vehicles signals that KLETKA’s core gameplay loop is evolving beyond “walk, fight, loot, descend.” Different traversal options create different viable playstyles. Some players might prefer vehicles for protection. Others might find them limit maneuverability. This design diversity keeps roguelike runs feeling fresh.
New Anomalous Floors Expand Level Variety
The update adds several new anomalous floors including the Junkyard, De Dirt 2, Funny Games, and Dogtown. Each represents a different environmental variation within the descent. Anomalous floors in roguelikes typically force players to adapt strategies—environmental hazards, unique enemy types, or layout variations that prevent relying on proven tactics from previous floors.
A new floor curse called “Flux” was also introduced, adding negative modifiers that challenge players further. These curses make runs more dangerous but presumably provide better rewards as compensation, maintaining roguelike risk-reward balance.
Cross-Platform Features Unify the Community
Beyond new content, the update adds cross-platform leaderboards and Rich Presence synchronized across Discord, Steam, and Epic Games Store. This is crucial infrastructure for co-op games because it lets players track statistics and compete against the entire playerbase rather than just their platform. Cross-platform leaderboards legitimize competitive engagement regardless of where players purchased the game.
Rich Presence across multiple platforms means friends on Discord, Steam, or EGS can see exactly what you’re playing, which floor you’re on, and potentially join if they own the game on a compatible platform. This social infrastructure encourages community engagement and helps players find compatible teammates.
New Boss: Rustbucket and Enhanced Audio Design
A new boss called Rustbucket joins KLETKA’s roguelike roster. Boss design in roguelikes is crucial because bosses represent skill checks and dramatic moments. A well-designed boss creates memorable encounters that players discuss and theorize about. Multiple new music tracks composed specifically for the Greenhouse Unit biome enhance the atmosphere. The composers include crystal lotus, houp, rofoshristo, PEX, Eskimo, sever4user, KNOWETSKI, and cycsl3k—demonstrating that audio design received dedicated attention.
New “Single Sensation” flood curse music by crystal lotus and two new cassettes by kosteal complete the audio additions. These details suggest the developers understand that roguelike atmosphere comes from more than mechanics.
Quality of Life Improvements and Fixes
Beyond new content, the update fixed numerous issues: incorrect enemy behavior where some enemies ignored players, live slime behavior problems, untranslated item descriptions, and the ability to bypass the Heart of the Gigastructure boss safely. The cosmic floor featuring a massive worm was restored. Flashlight intensity increased for better visibility. These fixes improve the core experience even without new content.
Journal entries were rewritten as more readable handwritten notes in both English and Russian. This attention to readability suggests developers care about accessibility alongside challenge.
Why This Update Matters for Early Access
KLETKA is in early access, making substantial content updates exactly what the community hopes for. Large biome additions, new bosses, vehicles, and cross-platform infrastructure prove developers are committed to building a complete experience rather than abandoning the game post-launch. The Greenhouse Unit update demonstrates serious expansion of scope—not just polishing existing content but genuinely expanding what KLETKA offers.
