Unity-focused team
Developers who work with the Unity engine day to day, not as a side skill.
Unity 3D game development for London studios and businesses
We build mobile, PC, console and VR games with the Unity engine — from first prototype through live-service support, scoped around your genre, platform mix and budget rather than a fixed package.
Built around your vision, not a template
Fulminous Software takes Unity 3D projects from concept through to launch and beyond, using current engine tooling to build visually polished, well-optimised games with reliable, smooth gameplay. Whether you're an indie developer, a growing studio, or an enterprise building a training simulation, scope is set to match your genre, budget and timeline — not the other way round.
- Custom Unity 3D game design built around your exact creative vision
- Multi-platform delivery across mobile, desktop, console and VR from a shared codebase
- Performance optimisation for smooth gameplay at target frame rates
- Advanced mechanics and live-service features where the project calls for them
- Continuous post-launch support so the game keeps performing after release

Unity 3D game development FAQs
Why choose Fulminous Software for Unity 3D game development?
We build tailored Unity 3D solutions, integrate advanced features and third-party tools where they genuinely add value, and provide ongoing post-launch support to protect your game's long-term commercial success.
How long does it take to develop a Unity 3D game?
A casual mobile game typically takes 6 to 14 weeks. A mid-level Unity 3D game takes 14 to 28 weeks. A fully-featured multiplayer or VR title takes 28 weeks or more. We work in fortnightly sprints so you see progress throughout the build.
Can you optimise our Unity 3D game for multiple platforms?
Yes — we specialise in cross-platform Unity 3D development, so your game works across iOS, Android, desktop, console and VR from a single shared codebase, saving both time and cost.
Do you offer post-launch support for Unity 3D games?
Yes — ongoing maintenance packages covering engine updates, OS compatibility patches, bug fixes, performance monitoring and new feature development to keep your game stable and growing after launch.
How much does Unity 3D game development cost?
It depends heavily on scope — a casual mobile game costs far less than an advanced multiplayer or VR platform. See the pricing table above for indicative GBP ranges, or book a free scoping call for an itemised quote.
Should I use Unity or a different engine for my game?
Unity is a strong default for mobile, cross-platform and VR titles thanks to its mature toolset and wide platform support. For projects where a different engine or an engine-agnostic approach fits better, see our broader 3D game development service.
