Sorcery is mountain racing in old Japanese cars. It's built on Initial Unity: Reborn and keeps what made it good: stylish arcade handling and proper racecraft on the touge.

On top it adds sector practice for the corner you keep losing time on, reworked online battles with synced starts, and replays cut like manga panels. Pick a car and you're racing down the hill in minutes.

Good questions

Is it free?

Yes. Initial Unity: Sorcery is free on Windows PC.

Is this an official Initial D game?

No. It's a fan project built on Initial Unity: Reborn, and it isn't affiliated with Initial D or its rights holders.

What do I drive with?

A wheel, a controller or a keyboard. There's an optional automatic gearbox if you'd rather not shift on a controller.

Can I race my friends?

Yes. Online battles have synced starts and hosts run their own lobbies, UGS matchmaking finds you a race, and Freeroam fits five of you on one pass.

How do the leaderboards work?

Every pass has Time Attack with its own board. Upload a run and you can race the ghost of the driver one place above you, and sector practice drills the corner you keep losing time on.

When can I download it?

The download goes up at launch. Once the Discord opens, it's where you'll hear first.
