The idea needs a playable proof quickly
Turn the core interaction or mechanic into a focused prototype before committing to larger production.
Game Development
Build the part of the game that needs to become real now.
Prototype mechanics, implement production systems and strengthen an existing team without pretending every project needs a full external studio.

Official GameFormatic trailerProblems we solve
Production often needs a focused implementation, not another planning document.
Game-development support is most useful when a concrete mechanic, prototype or system needs to move from idea to playable proof.
A system is blocking the rest of the team
Implement a defined gameplay, interaction or technical feature that other disciplines can build around.
The vertical slice needs extra specialist capacity
Add focused implementation where realtime art, VFX, tools and gameplay overlap.
The existing team needs co-development support
Take ownership of a clearly bounded production area while staying compatible with the current project architecture.
What we deliver
Focused development around a concrete production outcome.
The useful scope can be a prototype, a gameplay system, a technical proof or a vertical-slice contribution.
Rapid gameplay prototypes
Playable tests that answer whether the mechanic, interaction or technical direction works.
Gameplay & interaction systems
Defined systems implemented inside the existing Unreal Engine or Unity project.
Technical prototypes
Proofs for difficult realtime, rendering, interaction or content-production ideas before larger investment.
Vertical-slice & co-development support
Focused implementation where extra production capacity is needed for a bounded area.
Technology context
Development stays close to the realtime production stack.
The implementation can combine gameplay code, editor tooling, realtime art systems and production integration.
Unreal Engine
Blueprints, gameplay systems, technical prototypes, editor utilities and realtime integration.
Unity
C# gameplay, prototypes, editor tools and interactive system implementation.
Realtime content systems
Integration with VFX, materials, 3D assets, tools and performance constraints.
How the work runs
Reduce the idea to the smallest useful playable result.
01 Define the proof
Identify what must become playable or measurable for the task to be considered useful.
02 Prototype
Build the narrowest version that validates the mechanic or technical direction.
03 Integrate
Connect the implementation to the existing project architecture, content and production workflow.
04 Productionize
Harden the useful parts for continued development when the prototype is meant to survive beyond validation.
Relevant work
Show what became playable, testable or production-ready.
Work entries state the implemented responsibility and production context without claiming ownership of an entire external project.
Train Yard Builder — Experience Behind Trueway
At GameFormatic, Bartosz Rozmus worked across development, level design, art direction and 3D production. This supports focused implementation and co-development positioning without presenting the title as Trueway-delivered work.

Rapid PrototypingFAQ
Game development questions.
Can you build a complete game?
The strongest fit is focused prototyping, co-development and ownership of defined production areas. A full-project scope would need to be evaluated separately rather than assumed.
Can you work inside an existing Unreal or Unity project?
Yes. Specialist development support is designed to integrate with an existing codebase, content pipeline and team.
Can you build only a prototype?
Yes. A prototype can be deliberately disposable or prepared as the foundation for continued production, depending on the goal.
Start a project
Need a mechanic, prototype or system implemented?
Send the target engine, the part that needs to become playable and what the implementation must prove or unlock.

A short design description, reference or existing build context is enough to start defining a focused scope.
