The news may come as a shock as the last update for the game was released in 2011. The update was named The Pirates of Flying Fortress. As you already know, the developer plans to release another update in the second quarter of 2016. The update is named Call of the Tenebrae. This is a quite unexpected spring of the content for the game. You might think that these were all the news but no! Reality Pump also scheduled a development of Two Worlds 3 for the next 36 months!
Here is the site devoted to the upcoming DLC.
