Secret Level Studios

Secret Level Studios is an independent British video game development and co-development studio. It combines full-cycle development of original and licensed game properties with technical work-for-hire for external studios and publishing partners, covering engineering, art, gameplay implementation, porting, quality assurance and localisation.

The studio works primarily with Unity and C# architecture, applying custom tooling, procedural environment generation, shaders and lighting alongside stylized 3D character art, modelling, rigging and animation. Its technical services include adapting games for PC and contemporary console platforms, performance optimisation, compatibility testing and first-party certification support.

Development work

Secret Level Studios has contributed major quality-of-life updates and system refinements to Kitaria Fables, the farming action RPG originally developed by Twin Hearts. It also co-developed When the Light Dies, a dark-fantasy roguelite bullet-heaven game made with Electric Monkeys.

The company has moved into lead development on Kitaria Fables 2, working with original IP creator Twin Hearts and publisher PQube on the sequel for PC, PlayStation 5, Xbox Series X|S and Nintendo Switch 2. Alongside this partner-led work, it is developing its own original property, Project Outpost, a settlement-building game focused on trade, generational logistics and supply chains.

Company background

The business was incorporated in 2014 and adopted the Secret Level Studios name in 2023, following earlier periods as C3 Service Limited, C3 Services (UK) Limited and Fluid Design Technology Ltd. It remains an active, self-governed company with no parent company.

Its development approach spans proprietary projects and collaborative production, allowing the team to support partners from pre-production through release while building its own games for modern PC and console audiences.
