Unity 6 Game Development

Unity 6 is the latest generation of the engine that powers the majority of mobile games worldwide. Released in October 2024 with its most recent LTS update (6.3) arriving in December 2025, it brings meaningful improvements to rendering, multiplayer tooling, cross-platform support, and build pipeline efficiency.

For our team, Unity 6 is not a new starting point. It is the natural continuation of work we have been doing across every major Unity release for over two decades. Our director holds a Unity Certified Expert credential and has shipped titles ranging from server-authoritative MMORPGs to educational apps for language preservation. Unity 6 builds on that foundation with engine-level improvements that directly benefit the types of projects we deliver.

Whether you are starting a new project on Unity 6, planning a migration from an older LTS version, or need specialist engineers to help your team adopt the new tooling, we can help.

Better mobile performance out of the box. The GPU Resident Drawer and render upscaling technologies mean less time spent on manual draw call optimisation and more headroom on lower-end devices. For mobile porting and cross-platform projects, this translates directly into fewer optimisation hours and a smoother path to 60fps on budget hardware.

Improved multiplayer tooling. Netcode for GameObjects continues to mature, and features like the Platform Toolkit reduce the boilerplate needed to ship across multiple storefronts. For studios building co-development multiplayer titles, this means faster iteration and fewer platform-specific edge cases to debug.

Longer LTS support window. Unity 6.3 LTS is supported through December 2027, with an additional year for Enterprise and Industry subscribers. That gives live projects a stable, actively maintained foundation without being forced into premature upgrades.

Clear migration path. If your project is on Unity 2020, 2021, or 2022 LTS, the upgrade to Unity 6 is well documented and the API changes are manageable. Our legacy modernisation team has migrated projects across every major Unity version and can handle the rendering pipeline, plugin compatibility, and performance benchmarking work that a migration involves.

Our Unity expertise spans the full range of the engine's capabilities. Unity 6 is the latest chapter, not a fresh start.

Domi Online is a persistent MMORPG we built from the ground up using Unity and FishNet networking, supporting over 1,000 concurrent players with server-authoritative architecture, procedural world generation, and a custom 64-bit progression system. You can read the full breakdown in our Domi Online case study.

Our director spent two years at Jagex working on RuneScape Mobile, solving thermal throttling, memory pressure, and UI adaptation challenges on devices ranging from flagship phones to five-year-old budget Android handsets. That experience in performance optimisation informs every mobile project we take on.

We have also delivered educational games across multiple Unity versions for institutions including Cambridge University Press and The Language Conservancy. These projects require stability, accessibility, and long-term maintainability, all of which align well with Unity 6's extended LTS support model.

If your project is running on Unity 2020, 2021, or 2022 LTS, we can manage the full migration to Unity 6. Our process covers:

Not every project needs to migrate immediately. Here is how we think about it:

New projects should start on Unity 6. It has the longest remaining support window, the best tooling, and avoids a future migration entirely.

Projects on Unity 2022 LTS are stable and supported. If you are not planning a major update or a new platform release, there is no urgency to move. Continue shipping on 2022 LTS until your roadmap calls for a change.

Projects planning a major update or a port should seriously consider migrating as part of that work. Combining the migration with a planned development phase keeps costs down and avoids doing the same work twice.

Projects on Unity 2020 or earlier are on versions that have already reached end of life. If you are still actively developing or maintaining these projects, a migration to Unity 6 should be a priority.

If you are unsure, we offer a technical audit that assesses your project's specific dependencies, rendering pipeline, and plugin landscape to give you a clear recommendation. See our cost guide for general pricing context.
