# ForzaInfinity
Forza Horizon 2's online services, back for the PC version running on **Azimuth 0.9.10**
(recommended) or **0.9.9**, on Windows, Linux and the Steam Deck.
This repository holds the source of **everything ForzaInfinity runs on your PC**, so you can
see exactly what you install:
| Folder | What it is | Where it runs |
|---|---|---|
| `hook/` | `azimuth-tls.dll`: Azimuth's TLS helper replaced by a fork of ExtraOptions that sends the game's own online requests to a ForzaInfinity server. C, Kernel32 only. | Inside the game, on your PC |
| `dedicated/` | `dedicated_server.exe`: the free roam world a player hosts on their own PC (a relay of the game's NerdCore protocol), with STUN, UPnP and hole punching. Rust, std only. | On your PC, while you host a world |
| `release/` | The installers, updaters, uninstallers and the report script. | On your PC, when you run them |
The ForzaInfinity server (`https://infinity.anarqz.dev`) is not part of this repository. What it
receives from your game is what the hook sends, which you can read in `hook/adapters/`.
## Play
Download **ForzaInfinity.zip** from the latest release
and run `Install.cmd` (Windows) or `install.sh` (Linux / Steam Deck), or in one line:
 [code] 
 [code] 
Then start the game, open **Settings › INFINITY › CREATE PROFILE** and pick HARDCORE or NOOB.

## Checking what you run
- Every release lists the SHA-256 of `azimuth-tls.dll` and `dedicated_server.exe`
 (`*.sha256`), and both are signed with the project's Ed25519 key (`*.sig`). The hook only
 installs an update whose signature checks out against the public key built into it
 (`hook/adapters/azimuth_sign.c`), and only runs the relay whose SHA-256 it carries
 (`hook/adapters/azimuth_relay_hash.h`).
- Build the hook yourself: see hook/BUILD.md (`python build.py --azimuth`).
- Build the relay yourself: `cd dedicated && ./build-windows.sh` (see
 dedicated/README.md).
