## Experienced Unity Developer Needed for Isometric Action RPG / RTS Gameplay Prototype I'm looking for an experienced Unity developer (or someone proficient with another suitable 3D game engine) to help build a gameplay prototype for a new game concept. The objective is to rapidly prototype and playtest core mechanics before moving into full production. This is not a polished game development project. Instead, I want a functional prototype that demonstrates the gameplay systems and allows me to evaluate whether the mechanics are enjoyable and work well together. Placeholder assets are completely acceptable as long as the gameplay is smooth and easy to test. If the collaboration goes well, I expect to continue development through multiple prototype phases that could eventually lead to a larger, long-term project. ### Project Overview The game combines several genres into one gameplay experience: * Isometric action combat * Bullet hell mechanics * RPG progression * RTS-inspired squad control and positioning The goal of this prototype is to determine whether these mechanics complement each other and create enjoyable gameplay. ### Prototype Features **Bullet Hell System** * Modular projectile spawning system * Circular, spiral, cone, and wave attack patterns * Configurable bullet speed, direction, and firing intervals * Easy to expand with additional patterns **Player Controls** * Responsive isometric movement * Mouse aiming and keyboard movement * Testing multiple control schemes to determine what feels best * Smooth movement and aiming **Ally AI & Formation System** * AI-controlled allies that respond to player commands * Move to designated target locations * Maintain formations * Avoid collisions * Dynamic spacing between units * Basic RTS-style formation controls similar to Age of Empires **Enemy AI** * Basic tactical decision-making * Seek cover when appropriate * Position behind stronger allies * Decide whether to group together or spread apart * Simple flanking behavior * Basic target selection and movement logic ### Technical Requirements * Unity is preferred (other engines may be considered) * Target platform: PC * Clean, modular, and well-organized code * Placeholder graphics are acceptable * Systems should be easy to extend for future prototypes * Git version control is preferred ### Nice to Have Experience with: * Bullet hell or shoot-'em-up games * RTS AI or formation systems * Action RPG combat * AI state machines or behavior trees * Gameplay prototyping * Procedural gameplay systems ### Please Include * Portfolio showcasing similar projects * Relevant Unity or game development experience * Examples of AI systems, combat mechanics, or gameplay prototypes you've built * Estimated timeline for the first prototype * Hourly rate or fixed-price estimate I'm looking for someone who enjoys rapid gameplay prototyping and iterative development. If the initial prototype is successful, I'd like to continue working together on future milestones as the project grows.

Hi, For an isometric action RPG/RTS hybrid, the key is making combat, squad control, and enemy tactics feel fun together without the prototype becoming messy. I’d start by locking down the core loop: movement, aiming, firing patterns, ally commands, and basic enemy reactions. I can build a clean Unity prototype foundation with modular projectile patterns, responsive player control, formation movement, and simple AI states that can scale later. This will keep the code organized for future phases and make playtesting faster, especially when refining control schemes, spacing, pathing, and targeting. Initial focus: Core movement and mouse aim Bullet pattern system Ally command/formation logic Basic enemy behavior Simple test scene for playtesting Timeline: I can start immediately and deliver the first playable prototype in a short, focused phase, with room for quick iteration after testing. Would you like the first prototype to prioritize combat feel, or squad/AI behavior and formation quality?

The challenge in this prototype is not just building individual mechanics — it is making the combat, squad control, and AI systems feel connected and fun during real gameplay testing. I can help develop a modular Unity prototype with scalable gameplay systems including isometric controls, projectile patterns, enemy behaviors, ally formations, and extendable AI logic for future production phases. My focus would be on clean, maintainable systems that allow rapid iteration during playtesting rather than overbuilding unnecessary features at the prototype stage. Estimated first prototype timeline: 3–5 weeks depending on the final feature scope. I’d like to understand your preferred Unity version, target controls, and the minimum gameplay loop you want to validate first. Best regards, Ahtesham

Drawing upon my extensive 9+ years of Unity game development, I would relish the opportunity to bring your innovative Isometric Action RPG / RTS gameplay prototype to life. My overarching aim is to produce a non-polished, but smooth, easy-to-test, and demonstrative functional prototype with placeholder assets allowing for emergent evaluative insights into the project's elemental mechanics. What sets me apart as an ideal candidate is not only my adaptability to diverse genres such as bullet hell games but also my proficiency in developing comprehensive systems similar to your requests. For instance, I've created numerous bullet pattern designs - circular, spiral, cone and wave set, configurable speed and direction control - that I'd be happy to integrate into your game incredibly easy with Unity. Furthermore, due to my skill set surrounding territory management concept that I've developed for other projects which shares similarity with RTS movements (i.e., Age of Empires), complemented with a basic tactical decision-making AI system, unit spacing regulations and sponge effect usage strategy implementation are some of the strengths that qualifies me for your specific requirements. Lastly, the project structure will be entirely adaptable for future developmental iterations which is only essential for such fast-paced projects!

Hello, After reviewing your project requirements in detail, I fully understand the scope and expectations. I have experience developing gameplay prototypes, AI systems, and interactive applications in Unity, and I’m available to start your project immediately. I bring strong expertise in Unity, Unity 3D, Game Development, Gameplay Programming, Game Design, Game Testing, Game Programming, and Game Animation with over 10 years of experience. One of the key challenges in projects like this is building flexible gameplay systems that allow fast iteration while keeping combat, AI behavior, and squad mechanics easy to expand. I can create a modular prototype with bullet patterns, isometric controls, ally formation systems, enemy AI behaviors, and clean architecture suitable for future development. I have experience working with AI state logic, procedural gameplay systems, and Git-based development workflows for organized project management. I have a couple of quick questions: • Do you already have a preferred Unity version and project structure? • Should the first prototype focus mainly on combat feel, or should all AI and RTS systems be included in the initial milestone? I would be glad to help bring your gameplay concept into a testable prototype and continue through future development phases. Best regards, Carlos.

Hi, I have experience developing Unity gameplay systems, including character controllers, combat mechanics, AI behaviors, UI systems, and scalable game frameworks. This project is interesting because it focuses on validating gameplay ideas quickly, so the priority should be building smooth and flexible systems rather than spending time on unnecessary polish. I can help create the prototype with modular systems for bullet hell attacks, isometric player movement, aiming, RPG-style progression foundations, ally squad commands, and enemy AI decision-making. For AI, I can implement structured behaviors using state machines or similar approaches so enemies can handle positioning, flanking, targeting, and tactical movement while remaining easy to expand later. I understand the importance of rapid iteration for a prototype. I will keep the code clean, organized, and Git-friendly, using placeholder assets where needed so gameplay testing can begin quickly. If the core mechanics prove successful, the same foundation can continue into future development phases. I would be happy to discuss your design goals and help turn this concept into a playable prototype.
