The latest Guardians of Ember newsletter has been published on the Steam page to give players a bit of a heads up with regard to content coming to the game in the next couple of months. In April, Act V: Labato Fjord will arrive that brings nine new zones, sixteen new dungeons and a higher level cap. In May, players can look forward to Horde mode, a 5-player cooperative wave based survival mode.
The team also revealed issues with the current server host for North American players. As a result, the srever host will be changing soon in order to provide a better experience.
You can check out the full letter on the Guardians of Ember site.
