The K.A.S.: Kill and Assault old servers is un-active since the launch of 2.4.3 patch for game.
For security reasons , you need to create new account before play the game again.
You can download the patch here (for Windows).
You need 2.4.2 version installed to install correctly this patch.
The patch do not create any shortcut in your desktop , just install in the 2.4.2 version folder : "wFace Patch\db\games\kas1"
- Deactivate your antivirus before play the 2.4.3 version due to a false positive in the game servers.
if your antivirus block the connection , you can't play the game.
Good game!
Have a nice day =)
