From Tallinn With Voltage

Ghost Citadel was sketched in Tallinn, close to the industrial history of Soviet-era electronics and lunar exploration. The company is now incorporated in the United Kingdom and built around a European engineering mindset.

Our work connects game systems, data engines, hardware testing, and industrial software. The studio is small by design: fewer layers, clearer ownership, and stronger technical responsibility.


What We Build


Foundation

Linux and ARM first

Linux & ARM First

We care about hardware constraints early. If a build behaves well on modest Linux and ARM targets, stronger machines are a bonus.

Systems and story

Systems + Story

We build worlds, engines, and analytics around systems that can be inspected, measured, and improved.

Open by default

Open by Default

Open tools, clear exports, and explainable technical choices. Closed components must have a reason.

Evidence not hype

Evidence, Not Hype

Logs, profiles, benchmarks, and test builds matter more than slogans. The work must prove itself.
