@kingnightshadow I believe someone was saying 2019. Considering there is still talk that Mudrunner 1 has one last DLC, my speculation is we get the Mudrunner 1 DLC in the summer, and then around October or November we get Mudrunner 2.
Oct and Nov are popular for game releases, a lot of companies like to release around that time to cash in the Christmas shopping faze. So if it is 2019, then Oct-Nov would be the most likely release period.
