Aterdux announced yesterday:
More information.We expressed already our gratitude to all players who made possible development of our game and bought it on Early Access. But we think (and there is even a character in the game like that) that actions are more important than words. Therefore, we thank you all one more time and we are happy to announce that all who got the game on Early Access will receive as a gift extra content – map Road to the Iron Forest which is a prequel to the main campaing. This map is done already but not tested and not translated to other languages. We plan to add it to the game as DLC within the next few months.
