As the MMO market continues its march towards heavy saturation, it is our duty at MMO Fallout to inform you whenever another title sees its services come to an end. Gameforge has announced that they will be shutting down all support for the action MMO RaiderZ in its hosted territories. As Gameforge is merely the European publisher for the MMO, the game will remain operational in North America and South Korea where the game is published by Perfect World Entertainment and Neowiz Games respectively.
The FAQ published by Gameforge notes that RaiderZ did not meet financial expectations:
The success of RaiderZ did not meet our expectations and as we saw no other potential alternatives to the discontinuation of the services, unfortunately we were left with no other alternative than to take this step.
Servers will remain online until August 30th after which players who still want a fix will have to move over to Perfect World or Neowiz.
