Robot Entertainment has just revealed that Orcs Must Die! Unchained won’t be published in Europe by Gameforge anymore, with publishing right reverting to the developer on March 14, 2017. All European players will be able to migrate their accounts and this migration will allow players from North America and Europe to play together, as there will be a single Robot Entertainment account system.
The Gameforge Europe service will shut down on March 14 and the transition will take a week, with players able to transfer their accounts from March 21 onwards. All gold will also be transferred to Robot’s account.
You can read all the details about the migration on this FAQ.
