On September 4th 2016, Ubisoft shut down the authentication servers for Raven Shield. We use OpenRVS to point our clients at a new set of authentication servers so we can still play the game together.
1. Download the latest version of OpenRVS from [RVSGaming.org](http://rvsgaming.org/Downloads/).
2. Copy `openrvs.ini`, `OpenRVS.u`, `R6ClassDefines.ini`, and `Servers.list` to `<YourGameDir>/system`.
3. Edit `Servers.list` to choose which servers are displayed when RVSGaming servers cannot be reached. You can force the usage of this file by editing `openrvs.ini` and changing the value of `ServerListURL` to an invalid URL.
