I will create a 3d gameplay prototype in unreal engine
Rian Souza
About this gig
I create playable game prototypes focused on core gameplay, mechanics, and feel. My goal is to turn your idea into something you can actually interact with, test, and iterate on not just a concept sitting in a document.
Whether it's a combat system, movement mechanics, survival loop, or experimental gameplay idea, I build clean, functional prototypes that make your design decisions visible in real time.
I focus on responsiveness, structure, and fast iteration so you can validate gameplay direction without wasting time on overproduction.
What you get:
- Playable prototype built in Unreal Engine
- Core mechanics implemented and working
- Gameplay systems designed for testing and iteration
- Clean, expandable project structure
This service is for developers, designers, and creators who want to test ideas quickly, refine gameplay direction, and move from concept to something tangible.
A prototype here is not theory. It is a working system you can break, stress-test, and evolve into a full game.

FAQ
What exactly do you mean by a game prototype?
I build the core playable foundation of a game. The goal is to create a functional base where the main gameplay loop can be tested, felt, and iterated on.
Which engine do you use?
Unreal Engine (latest version by default). If you prefer a specific version, I can adapt if needed.
Can you work with my game idea or do I need a full design document?
I can work directly from your idea. A full design document is not required, but clear direction on what you want the prototype to focus on helps a lot.
What types of gameplay systems can you build?
My main focus is gameplay and combat systems, but I can also build other core mechanics depending on the project scope.
Do you provide art or assets for the prototype?
I use free placeholder assets only, just to represent the gameplay and test functionality.
Can the prototype be expanded into a full game later?
Yes. The prototype is structured in a way that allows it to be expanded and iterated into a full project if needed.
What do you need from me to start?
A clear description of the gameplay idea and what you want the prototype to focus on. The more direct the goal, the better the result.
Do you work with multiplayer systems?
Multiplayer is not my main focus, so I generally avoid it unless the scope is very simple.
Can you replicate a specific game mechanic or reference?
Yes. References from other games are useful and can be used as inspiration for building the mechanics.
What happens if my idea changes during development?
Minor adjustments are fine within the development window, but larger changes may require extra time or scope adjustment.
