Game Development Services

XGameDev builds custom Unity games and co-develops existing ones for clients, studios, agencies, and product teams. We work across mobile, desktop, WebGL, and browser-based HTML5 projects, with Unity as our main production engine and Construct or Phaser where a lightweight browser build is the better technical fit.

Our role changes with the project. Some clients need a full game built from a brief. Others need experienced Unity developers to take ownership of a feature, stabilise a codebase, improve performance, or help a project reach launch.

Unity Game Development and Co-development

We support game projects at implementation and technical leadership levels. That can mean gameplay systems, UI, tools, content pipelines, multiplayer integration, mobile performance, platform builds, store submission support, or production troubleshooting.

For studios, we can work inside an existing workflow and take responsibility for a defined part of the build. For non-game companies and agencies, we can provide the game-engine expertise needed to turn a concept into a playable, maintainable product.

Platforms and Engines

For mobile, desktop, and WebGL games, we usually build with Unity and C#. For HTML5 games, interactive 2D animations, and playable advertising content, we use lighter browser-focused tools such as Construct, Phaser, HTML5, CSS, and JavaScript.

The engine choice should follow the product. A Unity build may be right for 3D, cross-platform deployment, simulation, or complex runtime systems. A smaller HTML5 stack may be better for simple 2D interactions, campaign content, or LMS delivery. See our Unity vs. Unreal Engine comparison if Unreal is also on the table for a graphics-heavy build.

Production Support Beyond Gameplay

Already have a game and want to reach another platform? Our game porting service covers mobile, desktop and WebGL adaptations, including controls, interface changes, performance and release integrations.

Game delivery often depends on systems outside the moment-to-moment gameplay. XGameDev can also support backend services, multiplayer systems, analytics, build automation, native mobile integrations, App Store and Google Play releases, and ongoing technical maintenance.

Examples of Game Work

Our portfolio includes mobile FPS titles, educational games, browser games, virtual worlds, interactive ads, puzzle games, and client-funded prototypes. Where project details can be shared, the portfolio pages explain the product context and the technologies involved.

From brief to release

Start with the player experience, target platform, existing art and code, deadline and available budget. We use that to define a playable milestone, identify technical unknowns and agree what the first build must demonstrate. Multiplayer, content volume, custom artwork, supported devices and external integrations are major estimate drivers.

Before production, agree milestone acceptance criteria and who supplies design, art, audio and store materials. At handover, the scope should identify source access, build instructions, licensed assets and release accounts. Post-launch bug fixing, content updates and backend operation need an agreed support arrangement.

Do I need a complete design document?

No. A short brief and references can start the discussion. If the core interaction is still uncertain, a prototype can answer that question before a larger production commitment. If you already have a team and need a defined system delivered, co-development is the more specific route.

Choose a focused first step

For an early concept, see game prototyping. If your brief is driven by an audience outcome, explore serious and educational games or branded campaign games. Our project brief guide and template help capture the inputs for an estimate.
