MITIGATIONS PROVEN UNSAFE. MONITOR #7 FOR UPDATES

PLEASE DON'T SHARE THIS PROJECT IN PUBLIC. YES, SHARING JUST THE NAME IS "SHARING" TOO

Regions

Experimental mitigations currently only available for OS

Information

The Game's anticheat is fundamentally incompatible with Wine in multiple ways (at least 3). This patch removes it entirely and imitates it's behaviour. This is much more radical than classical micropatching, so the risks are probably higher. Please contact me if you want to know how the patch works.

The game also requires DirectX shared resources, which will probably never be fully supported by DXVK/WineD3D. The patch forces Unity to not use DirectX shared resources in a rather hacky way. This might cause graphical glitches.

And no, it does not work on Windows.

Installation

Wine 8.0+ (staging branch) is recommended to run the Game. Older Wine versions will probably work as well. DXVK is recommended, but not required.

The Honkers Railway Launcher can be used to install and patch the Game automatically. If you don't want to use the launcher, follow the manual installation instructions below.

macOS users: Yaagl can be used to install and patch the Game automatically.

Mitigations are currently not supported by any third-party launchers

Manual installation:

• Download and install the Game from the official website. Do not launch the Game
• Clone this repo (not into the game directory!) and switch to the mitigations branch: git clone https://notabug.org/mkrsym1/astra && git checkout mitigations
• Open the game directory in your terminal
• Install the patch: install.sh --patch-data /some/directory. /some/directory is the directory where the patch files will be copied to (MUST BE OUTSIDE OF THE GAME DIRECTORY. MAY RESULT IN A BAN OTHERWISE). Use install.sh --root-cmd <command> to use something else instead of polkit

Please start the game ONLY using launch.bat

Guidelines

1. Please don't share this project in public. This might attract unnecessary attention from either the Game Company or the Anticheat Company
2. Please don't abuse this project for cheating. We're just trying to play the Game through Wine

Troubleshooting

Please do not report any issues with the Game to the official channels. Use the issue tracker of this repository

Refer to TROUBLESHOOTING.md for the list of known issues.
