I’m moving an original top-down tactical shooter from design docs into full production and need an experienced Unity developer to take the technical lead. The game is headed to both iOS and Android, will run a single-player campaign, and relies on lively AI-controlled enemies to keep the action sharp. Your role covers the entire Unity-side pipeline: laying down a clean, scalable architecture, integrating assets and animations, building reliable AI behaviour trees, and tuning touch-screen controls so they feel instantly familiar on phones and tablets. Throughout the project we’ll work against fixed-price milestones, and on final acceptance all source code, project files, and related assets transfer to me along with full IP ownership. I already have GDDs, level sketches, and reference art ready to share. We’ll iterate in short sprints: prototype → vertical slice → content build → polish → store-ready release. Each milestone will ship a playable build and commented source in a Git repository, plus brief technical notes so the hand-over stays painless. If you have a track record launching Unity titles on both App Store and Google Play—and you enjoy squeezing every last frame out of mobile hardware—let’s talk timelines and kick this off.

Moving from design docs into production is usually where mobile shooters either stay maintainable or become difficult to extend later, so I’d start by putting the gameplay architecture in place before building content. The first milestone would focus on a playable prototype with core combat, enemy spawning, pathfinding, and touch controls that already reflect the feel you’re targeting. From there, I’d build the AI layer around behavior trees so enemy actions remain easy to tune as new enemy types are added instead of hard-coding logic per character. For the vertical slice, I’d integrate animations, weapon systems, progression flow, and performance profiling early on. Mobile shooters often feel fine with a handful of enemies, then struggle once encounters become dense, so I prefer measuring frame time continuously rather than leaving optimization until the end. I’ve worked on several mobile projects where clean Git handovers and documented milestones were part of the delivery process, so the ownership transfer requirements fit well with how I work. Do you already have a preferred solution for multiplayer-style enemy navigation (Unity NavMesh, A* Pathfinding, or custom), or would you like that recommendation made during prototyping? I’m ready to start with the prototype phase.

✅ 1. Is the tactical shooter planned as 2D sprites, 2.5D, or full 3D top-down with NavMesh/physics? ✅ 2. Should enemy AI use behavior trees, GOAP, or a lighter state-machine system for mobile performance? ✅ 3. Do you already have target device specs, art/animation formats, and backend/store-service needs? I’d begin with a playable prototype focused on controls, camera, shooting loop, enemy perception, and frame budget. The biggest risks are mobile input feel, AI cost, asset memory, pathfinding spikes, and scope creep across campaign content. Milestones should ship builds from prototype to vertical slice, content pass, polish, and store release.

You mentioned lively AI-controlled enemies. Do you have a preference for a specific AI framework, like Behavior Trees or a Goal-Oriented Action Planning (GOAP) system, or is that part of the initial architecture I will define? I understand your requirement for a lead Unity developer for a top-down mobile tactical shooter. With extensive experience in full-cycle mobile game development (iOS/Android) and a strong background in AI systems, I’m confident I can deliver a solution that meets your goals. One of my recent projects involved building a 3D stealth action game for mobile from the ground up. The system required: - Developing complex AI patrol and combat logic using Behavior Trees. - Implementing and tuning responsive dual-stick touch controls for fluid gameplay. - Optimizing performance across a wide range of iOS and Android devices to hit 60fps. This experience is directly relevant to your project, especially with regard to building robust AI, tuning controls for mobile, and ensuring a performant, scalable architecture. I focus on building systems that are: - Scalable and production-ready - Secure and maintainable - Easy to extend with future content My approach is agile and detail-oriented. I'm ready to review the GDDs and start on the first sprint. Let’s connect and discuss the timeline. Best regards, Philip O.

Hi there! You are taking a top-down tactical shooter from design into production, and the real challenge is building a scalable Unity architecture that keeps AI, touch controls, and mobile performance working smoothly as the game grows through each milestone. I have developed Unity gameplay systems and mobile game prototypes with clean, modular architecture, AI behaviors, and optimized performance for Android and iOS. My experience with iterative development and Git-based workflows ensures every milestone delivers a stable, playable build that is easy to expand and maintain. I will lead the Unity development from prototype through release, implementing modular gameplay systems, intelligent enemy AI, responsive touch controls, optimized mobile performance, and well-documented source code that transfers with full IP ownership at project completion. Check our work: https://www.freelancer.com/u/ayesha86664 Are you planning to use Unity Behavior Trees, the NavMesh system, or a custom AI framework as the foundation for enemy decision-making throughout the campaign? I am ready to start — just say the word. Best Regards, Ayesha

Absolutely, taking an original top-down tactical shooter from design docs into production is exactly the kind of Unity technical leadership work that benefits from clean architecture, disciplined pipelines, and mobile-first performance tuning. I will own the Unity-side end-to-end build: establish a scalable project structure, integrate assets and animations into a maintainable workflow, implement and tune AI behavior trees for lively enemy control, and design responsive touch-screen controls that feel instantly familiar on iOS and Android. The campaign will remain single-player, with a focus on reliable gameplay loops and consistent frame pacing across devices. We’ll follow your milestone cadence (prototype → vertical slice → content build → polish → store-ready release). Each milestone will deliver a playable build plus commented source and project files in a Git repository, along with concise technical notes to keep hand-over painless at acceptance, where full IP ownership and asset transfer are included. Let’s move quickly from GDDs, level sketches, and reference art into an efficient vertical slice, then iterate in short sprints toward an App Store / Google Play release.
