[Source] Launching into Closed Beta around the same time last year, Gameforge has announced that RaiderZ Europe will be shutting its doors on 30th August 2013. The reason given was “the success of RaiderZ did not meet our expectations and as we saw no other potential alternatives to the discontinuation of the services.”
A superb alternative to TERA (when it was Pay to Play), RaiderZ was arguably the best F2P action MMORPG on the market. Of course, I am guessing the population dropped drastically after users switched to TERA Europe when it went F2P, also under Gameforge.
