Katana is in the game and is sold by Mr. White. Cybernetics are planed, but I will have to make the Ark settlement before that. I'm just working on the graphics in the meantime and thought it would be nice to put them in the cover image as a small sneak-peek.
Those things were in the initial public versions, but I took them out. They took too much space and they became slightly obsolete since now your character can comment on those things at the start of each week.
