Roadmap

Where Phaethon stands, and where it goes next.

Now

Where it stands.

All four games are playable. Jak X: Combat Racing, which OpenGOAL never ported, plays from its first race to its credits.

The first release.

The first release is about polish across all four games. It ships when it is ready, not on a date.

After that

What comes after.

Achievements for all four games
Online multiplayer for Jak X
First-class mod support
Steam Deck
macOS

None of these has a date.

Built with AI in the loop. Phaethon uses AI assistance for speed and accuracy, and holds it to the same bar as every other contribution: every change is read, tested and checked against the console before it lands.
