More about the Rainbow Six Siege X Test Server
The current Siege X test server primarily highlights the Dual Front game mode. As a result, the Core Siege matchmaking is disabled. To play with friends, head to the Dual Front mode and try out the new District map and everything new that this new primary game mode has to offer.

Furthermore, Siege X test server packs a new benchmark run to accompany the new system requirements released ahead of Siege X launch. This new benchmark run will allow players to get an idea on what kind of performance to expect upon Siege X release.
