UEFN GAME DEVELOPMENT / DIRECT DEVELOPER PARTNERSHIP
FROM CONCEPT TO IMPROVEMENT.UEFN GAMES BUILTDIRECTLY BY THE DEVELOPER.
12 games shipped · 7M+ total plays · 9,303 peak CCU
Nearly three years of hands-on UEFN production. The same developer handles planning, level design, Verse, bots, testing, launch, and post-release improvement.

PROVEN BY SHIPPING
Hands-on experience across planning, production, launch, and improvement.
PROJECT FIT
When ZyrenStudio is a good fit
Turn an idea into a UEFN game
We can structure the concept and core experience even before every specification is fixed.
Bring in focused Verse expertise
Custom rules, rounds, win conditions, loadouts, and other systems are translated from requirements into implementation.
Validate feasibility first
When UEFN limitations are uncertain, Specification & Technical Validation can de-risk the full build.
Outsource the UEFN portion of a larger project
Studios and agencies can engage ZyrenStudio for a focused production phase or Verse implementation.

DIRECT01DEVELOPER
SOLO EXPERT STUDIO
THE PERSON YOU SPEAK WITH
BUILDS THE PROJECT.
ZyrenStudio is a specialist UEFN brand operated by one developer. There is no handoff from sales to production: the developer behind 7M+ total plays handles the conversation and the build directly.
Nearly three years in UEFN
Continuous hands-on experience across building, publishing, and improving games.
Direct design-to-build thinking
Gameplay goals and technical feasibility are evaluated together.
Validate before overpromising
Uncertain features can be checked through technical validation and, when needed, a small PoC.
Specialist production is scoped
If custom assets or outside specialists are required, scope and cost are confirmed first.
CAPABILITIES
ONE CONTINUOUS PATH,
FROM IDEA TO IMPROVEMENT.
Scope can cover a full game or a focused technical component.

PHASE 01 / DISCOVERY
BEFORE WE BUILD,
WE DEFINE WHAT AND HOW.
For new games and custom systems, production does not begin with assumptions. We first organize the game specification and the UEFN implementation approach. When needed, hands-on validation clarifies feasibility, constraints, and the production scope before full development.
Specification & Technical Validation
From ¥100,000- ✓Game specification
- ✓Required features and priorities
- ✓UEFN implementation approach
- ✓Technical feasibility
- ✓Small PoC when required
- ✓Constraints and alternatives
- ✓Full-development scope
- ✓Development process
- ✓Formal quote
This phase may be skipped when a sufficient specification already exists and there is no meaningful technical uncertainty.
Primary deliverables
Depending on the project: game specification, feature list, implementation approach, validation results, constraints and alternatives, full-development scope and process, and a formal quote.
When full development follows
When ZyrenStudio continues into full development, the base ¥100,000 fee is applied to the full-development budget. The specification fee is not charged twice.
Schedule
The timeline is confirmed before the phase begins after the research and validation items are reviewed.
ENGAGEMENTS
TOTAL BUDGET,
TWO CLEAR PHASES.
Simple UEFN Game
Specification & Technical ValidationFrom ¥100,000
+Full DevelopmentFrom ¥200,000
A small game built primarily with standard Fortnite devices.
New UEFN Game Development
Specification & Technical ValidationFrom ¥100,000
+Full DevelopmentFrom ¥600,000
Concept, map, game systems, testing, and launch handled as one engagement.
Full Custom Development
Specification & Technical ValidationFrom ¥100,000
+Full DevelopmentFrom ¥1,100,000
A fully developed game combining custom rules and multiple systems.
Business and Promotional Projects
Specification & Technical ValidationFrom ¥100,000
+Full DevelopmentFrom ¥1,900,000
For companies, studios, agencies, brand campaigns, and events.
The total budget combines Specification & Technical Validation and full development. The validation phase may be skipped when the specification is sufficient and the implementation is clear, or for a very simple game based on standard Fortnite devices. Final pricing depends on scope, features, assets, and timeline.
PROCESS
FROM FIRST BRIEF
TO LIVE IMPROVEMENT.
Free Consultation
We confirm the game idea, goals, budget, and preferred timing.
Overview and Budget Range
We assess the project scale, recommended route, and approximate budget range.
Specification & Technical Validation
When required, this phase starts from ¥100,000 to define the game specification, implementation approach, and technical feasibility.
Final Specification and Quote
We confirm scope, deliverables, review methods, exclusions, and the formal full-development quote.
Full Development and Reviews
Production follows the confirmed specification with reviews at meaningful milestones.
Testing and Launch
The experience is playtested, adjusted, and prepared for release.
Analyze and Improve
Post-launch data can inform a separate improvement phase.
SCOPE & LIMITS
WHAT WE BUILD,
AND WHAT WE VERIFY.
UEFN platform constraints
Not every requested feature is possible in UEFN. Uncertain areas can be addressed through Specification & Technical Validation.
Post-launch outcomes
Epic review, Discover placement, play counts, and revenue cannot be guaranteed.
Assets and specialists
Paid assets or specialist production are identified and quoted before they are added to scope.
FAQ
Questions before you inquire
01Can I inquire without a finished specification?+
Yes. The free consultation confirms the project overview, budget range, and the right next step. Detailed specification work is handled through Specification & Technical Validation when required.
02What if I do not know whether a feature is possible in UEFN?+
Specification & Technical Validation can clarify uncertain functionality and include a small PoC when hands-on verification is required.
03Can you build every genre and advanced system?+
No blanket claim is made. We review the concept and required features, then communicate feasibility honestly.
04Can I hire you only for Verse or an existing project?+
Yes. The quote is based on the required functionality, current project state, and expected deliverables.
05Do you support NDAs?+
Yes. Select the NDA requirement in the inquiry form and we will confirm the next steps.
06When is pricing finalized?+
The free consultation provides an approximate range. When Specification & Technical Validation is required, the formal full-development quote follows after that phase confirms the scope.
07Can you support post-launch improvements?+
Yes. A follow-up scope can be defined around player data and specific gameplay improvements.
08Are plays or revenue guaranteed?+
No. Past results demonstrate experience but do not guarantee future placement, play counts, or revenue.
