Starsector 0.97a is out! (02/02/24); New blog post: Anubis-class Cruiser (12/20/24)
As much as I'd like a bit more work put into missions (some really special ones, a way to make custom ones in-game and so on), I really think Alex should first focus on finishing the campaign stuff and getting the game to 1.0 hopefully and then IF he feels like adding more missions. Because it's honestly not something crucial that the game needs, it would just be an extra.
TBH, I was hoping for real missions in the campaign with lore tie-ins/implications. I think that might also be slightly more likely than an update of the missions in the menu.
