Unity Game Development

Before any development begins, we invest time in understanding your requirements, constraints, and commercial objectives. This phase includes requirements gathering and brief refinement, technical feasibility assessment (platform targets, engine selection, performance budgets), and scope definition with milestone deliverables. We produce a detailed project proposal with budget and timeline estimates broken down by phase. If you want to prepare before our first conversation, use our Game Development Cost Estimator for an instant ballpark figure and our Timeline Estimator to understand likely delivery windows for your project type.

Pre-production is where the project's technical and creative foundations are established. We create or refine the Game Design Document (GDD), define the art direction and style guide, plan the technical architecture and infrastructure, and build Unity greybox prototypes to validate core mechanics before committing full production budget. This phase also includes risk identification and mitigation planning. We flag technical risks early (multiplayer synchronisation challenges, target device performance constraints, third-party SDK limitations) and plan around them before they become expensive mid-production surprises. See our Game Design services for more detail on our design process.

Production follows an agile sprint model with 2-week delivery cycles. Each sprint produces a playable build you can review and provide feedback on. We use continuous integration with automated build pipelines so every code change is tested before it reaches a milestone build. You get full access to project management tools (Jira), build servers, and version control (GitHub), so you can track progress in real time. QA runs continuously throughout development, not as a separate phase at the end. Every feature is tested as it is built, and regression testing ensures new work does not break existing systems.

We handle platform submission management for Apple App Store, Google Play, Steam, and console certification (PlayStation, Xbox, Switch). This includes store listing preparation, age rating classification, compliance review, and the technical submission process itself. Our App Store Launch service covers this in full detail. Post-launch, we provide monitoring and hotfix capability for launch-day issues, analytics review to identify player behaviour patterns and performance bottlenecks, LiveOps support for content updates and seasonal events, and ongoing balance tuning based on real player data. We offer these as retainer arrangements so your game continues to improve after release.

Casual, mid-core, educational, and serious games built for touch-first interaction. We optimise for device fragmentation, battery life, and the short-session patterns of mobile players. Recent mobile projects include Pocket Factory (idle tycoon for Mojo Games), Nova Blast (Android port for Foil Hat Games), and Nub (arcade game for Inferna Games). See our Mobile Game Development service for full details.

Indie, strategy, simulation, and multiplayer titles built for Steam and Epic Games Store. PC development allows for deeper systems, more complex UI, and longer session design. Domi Online is our largest PC project: a full MMORPG with real-time multiplayer, a player-driven economy, and server-authoritative architecture supporting 1,000+ concurrent users.

We port existing titles to console and develop native console builds. Console development requires platform-specific certification, input scheme adaptation (gamepad support, UI navigation), and performance targets mandated by each platform holder. Our Console Porting service handles the full certification and submission process.

Educational games, marketing interactives, and legacy content rebuilt for modern browsers. WebGL deployment through Unity or native HTML5/Canvas reaches users without app installation, making it the preferred platform for schools, museums, and corporate environments. Our Legacy Modernisation service specialises in converting Flash content to HTML5 and Unity WebGL.

Real-time and turn-based multiplayer ranging from small lobby-based games to MMO-scale persistent worlds. We build server-authoritative architectures using FishNet, Mirror, and Photon Fusion, with dedicated server deployment and management. Cross-platform play (mobile vs PC, console vs PC) requires careful input balancing and matchmaking design, both of which we handle.

We apply game engine technology to non-entertainment applications: gamified corporate training and onboarding platforms, interactive educational content with LMS integration (SCORM, xAPI), brand activations and marketing experiences, and simulation and visualisation tools. Our Educational Games service covers our institutional and EdTech work in detail.

We have 10+ years of Unity development experience across mobile, PC, console, and WebGL. Our team holds Unity Certified Expert Programmer credentials and works with advanced engine systems including ECS/DOTS for high-performance data-oriented design, Addressables for dynamic content loading and memory management, Shader Graph and VFX Graph for visual effects, the new Input System for cross-platform input handling, and Unity Gaming Services for backend infrastructure. We are actively developing with Unity 6, taking advantage of its improved rendering pipeline, GPU Resident Drawer, and Multiplayer Center for streamlined networking setup.

We have shipped multiplayer games at every scale, from 2-player local co-op to MMO-scale persistent worlds. Our networking experience includes FishNet (our preferred framework for new projects), Mirror, and Photon Fusion. Every multiplayer implementation uses server-authoritative architecture to prevent cheating and ensure fair play. For Domi Online, we built networking infrastructure supporting 1,000+ concurrent users with real-time combat, player-to-player trading, and a server-validated economy where every transaction is verified to prevent item duplication and currency exploits. We handle dedicated server deployment, scaling, and management through PlayFab and custom infrastructure.

Performance is a core competency, not an afterthought. We profile CPU, GPU, and memory usage throughout development, not just at the end. Our optimisation techniques include GPU instancing and draw call batching for rendering performance, LOD systems and occlusion culling for scene complexity management, memory profiling and object pooling for constrained mobile platforms, and thermal management and battery optimisation for sustained mobile play sessions. Our team's experience optimising RuneScape Mobile for mid-range devices directly informs how we approach every mobile project. See our Performance Optimisation service for our full optimisation methodology.

Our founders bring experience from Jagex (RuneScape, one of the largest MMORPGs ever made) and Fish in a Bottle (educational games for Cambridge University Press, BBC, and the Museum of London). That background gives us the technical rigour of AAA production combined with the agility of a specialist studio. We hold Unity Certified Expert Programmer credentials and have a combined 20+ years of professional game development experience.
