Install guide
- Make an account on the Register page and activate it from the e-mail.
- Download the client package (about 3 GB). Right-click it → Extract All... and type exactly
C:\ToxicCo-Clientas the folder. It must be that folder, otherwise the game won't start. - Open
C:\ToxicCo-Clientand double-click ToxicCoLauncher.cmd (tip: Send to → Desktop to get a shortcut). If nothing appears, double-click CoLoader.exe instead. - Pick Fullscreen 1920x1080, Windowed 1920x1080 or Windowed 1024x768. Don't use play.exe or AutoPatch.exe from the old client.
- On the login screen pick any server in the list, then log in with your website username and password.
Antivirus warning? The ToxicCo loader starts Conquer.exe and loads a small DLL into it (that is how the client finds our server). Some antivirus programs flag every tool that does this. Only allow it if you got the package from this site.
Minimum specs
| OS | Windows 10 or 11 (64-bit is fine, the game runs as 32-bit) |
|---|---|
| CPU | Any dual-core from the last 10 years |
| Memory | 4 GB RAM |
| Graphics | DirectX 9.0c compatible GPU |
| Disk | About 10 GB free while installing (3 GB download + 6 GB game) |
| Internet | Broadband; the server runs in one data centre, so ping depends on where you live |
Guideline for an old 2D client, not a measured benchmark. Mac/Linux: not supported officially; Wine may work.
