FLOOR ZERO: ZOMBIE ROGUELIKE
DESCEND. SURVIVE. REBIRTH.
A cooperative zombie survival roguelike that pushes players to their limits. Navigate through randomly generated floors of terror, where survival is never guaranteed and death is just the beginning of your next attempt. Built for the modern gaming generation that craves authentic challenge and progression through meaningful cooperation. Floor Zero is designed as a showcase of UEFN’s most cutting-edge systems — leveraging Scene Graph for modular, randomized floor design that feels handcrafted yet infinitely scalable. It proves what’s possible today, while being future-proofed for what’s coming next.
Cooperative Survival
Team up with friends in a relentless fight for survival. Communication and coordination are your only weapons against the undead hordes.
Infinite Replayability
Built in UEFN with random floor generation. Every descent into darkness brings new challenges, layouts, and terrifying encounters.
Unforgiving Stakes
Every choice matters. Every resource counts. One wrong move could mean the difference between salvation and becoming another victim of Floor Zero.
The Concept
Players start on a rooftop base camp of a doomed skyscraper. From there, the only way out is down. Each floor of the tower is randomly generated, filled with escalating threats, brutal encounters, and unpredictable modifiers that force players to adapt on the fly. The elevator never goes back up — survival depends on making the right choices at the right time. After each floor, players earn powerful cards, loot, or risky shortcuts that shape their run. Every descent tells a new story of survival, cooperation, and inevitable sacrifice.

Key Features
Elevator Hub
A safe checkpoint between chaos. Customize your personal elevator with cosmetics and modifiers, prepare for the next descent, or face rare malfunctions that trigger horror-like side events.
Card & Boon System
Each run is shaped by the cards you collect — buffs, elemental perks, NPC favors, or utility upgrades. Build synergies on the fly and adapt to whatever the RNG throws at you.
Randomized Floors
Every descent is unique. Floors randomize layouts, zombie spawns, and modifiers. Rare events and elevator malfunctions break routine and keep players on edge.
Persistent Progression
Unlock faster leveling, permanent NPC allies, elevator and base camp cosmetics, and rebirth-exclusive upgrades. Progression fuels replayability without trivializing challenge.
Risk vs. Reward
After clearing the building, either escape with your rewards or descend into even deadlier sub-levels. The deeper you go, the greater the prizes — and the higher the stakes.
Co-op Scaling
Survive solo or in squads. Difficulty scales with player count, while solo runs remain balanced. Cooperative trading of cards, chips, and loot adds layers of strategy.
Built for the Future of UEFN
Scene Graph
We’re using the latest of UEFN's tools — Scene Graph’s prefab system to build modular, randomized floors that can be duplicated, iterated, and remixed for infinite variety. This ensures that every run feels handcrafted while remaining endlessly scalable.
Persona Device
NPCs in the rooftop base camp and within floors will come to life with natural voice, memory, and distinct personalities. Survivors rescued mid-run can remember player choices, adding immersion and narrative depth.
Custom Items & Inventories
We’re laying the foundation for unique loot systems, consumables, and progression items beyond standard Battle Royale gear. Every card, modifier, or rare consumable will feel like a custom creation designed specifically for roguelike runs.
Custom Weapons
With Epic’s upcoming support for creator-made weapons, we’ll design firearms and melee gear from the ground up. Weapons can evolve dynamically within a run — gaining new firing modes, elemental properties, or unique mechanics tied to the card/boon system.
Dynamic NPCs & Boss Encounters
Dynamic NPC Survivors
Players will encounter unique NPCs throughout the tower. Some can be rescued to join the rooftop base camp, unlocking shops, buffs, or quests.
Persona Device Integration
When released, NPCs will utilize the new Persona Device to deliver natural, voiced dialogue that reacts to player actions and run state. This gives survivors and quest-givers true personality.
Dialogue & Cinematics
We will combine the Dialogue Device with short in-game cinematics to immerse players in story moments — like elevator malfunctions, survivor rescues, or boss introductions.
Custom Boss Encounters
Bosses will feature bespoke mechanics powered by Verse: attack patterns, unique VFX, special arena modifiers, and animation-driven abilities (charges, slams, ranged attacks).

Giving Back to the UEFN Community
As part of Floor Zero's development, we plan to give back to the UEFN creator community by publishing regular Dev Logs. These updates will share technical insights, Verse code snippets, and lessons learned from building a large-scale roguelike system in Fortnite.
By making our development process transparent, we aim to help other creators learn how to use Epic's latest tools — like Scene Graph, Persona Device, and Custom Weapons — in their own projects.
Building a Thriving Community with Epic's Tools
Epic's Creator Communities Feature
Epic is introducing "Creator Communities" — new official forums where creators can share updates, events, and request feedback, visible from Island Pages, Creator Pages, Discover, and Island Lobbies.
Floor Zero will fully leverage this system.
Our Community Plan
  • Create regular posts and updates using the new Creator Communities tools (screenshots, dev logs, "question of the week", etc.)
  • Drive our Discord/players toward following our Creator Page so they see updates directly in Fortnite
  • Use feedback requests via forums/community posts to inform balance, new cards, modifiers, cosmetic design
  • Hire community manager to moderate & engage, ensure players feel heard
  • Use notifications to alert followers of new content, events, sales — increasing retention and engagement
By integrating with Epic's Creator Communities, Floor Zero will not just build a game; we'll build a lasting community where players are involved in the game's growth and evolution.
