What Engine Does Star Wars Zero Company Use?
Short answer
The game runs on a custom engine developed by Bit Reactor, the studio founded by XCOM veterans. It is not Unreal Engine, and it is not Unity. The engine has no publicly confirmed name.
A custom engine instead of Unreal or Unity
Technical reference pages and coverage of the game confirm the Bit Reactor custom-engine answer. That places Zero Company outside the two engines most PC releases rely on — a deliberate studio choice consistent with Bit Reactor’s background building tactical games.
Why a custom engine
The studio’s pedigree explains the choice. Bit Reactor was built around developers from the XCOM line, and its engine is designed around the specific needs of turn-based tactical play: precise grid and cover systems, squad-scale AI turns, and — visibly in this game — deep character customization with thousands of armour combinations rendered in-engine. A purpose-built engine lets those systems be first-class rather than bolted onto a general-purpose framework.
What remains unknown
Because the engine is proprietary and young:
- No confirmed engine name has been published by the studio.
- Technical capabilities are not formally documented outside what the shipped game demonstrates.
- Coverage notes the possibility it builds on modified prior in-house technology; nothing official confirms either way.
The launch-week performance issues on PC also make this a live question — custom engine optimization at launch is exactly where rough edges show, and patches will reveal how quickly the tooling matures.
FAQ
Is it Unreal Engine?
No. The game uses Bit Reactor’s custom engine.
Is it Unity?
No.
What is the engine called?
No name has been publicly confirmed.
Why does the engine matter for players?
Right now it shows in the PC performance picture — launch-week optimization issues are consistent with a young custom engine, and patch cadence will tell the rest of the story.
