Hey there! Really glad to hear you're enjoying the game so far. Please drop me a line if you finish your video as I'll be well up for watching that.
Wanderstock's next mission will be available very soon. I'm still finishing up the second half of the story missions and players who have purchased Total Anarchy through Steam or Itch can expect new story content in the next 1-2 weeks. Subscribe to the page to get an update when that's ready. Your save file should also remain compatible so you can pick up where you left off.
Congrats for getting this far so quickly - I hear a lot of players are finding the missions punishingly difficult!
