Hey,
i would like to see that you can place corridors like you can place walls in several rts titles.
You just e.g. shift+leftklick on one point and then drag the corridor the way you want it to go if you release shift you can change direction of the placement so you can make "L-Corridors", pressing shift again lets you change placement direction again.
In addition to that it would be cool if you can start placing corridors on the edge of existing corridors, so that it autmoatically cuts the wall of the existing corridor and starts adding the new corridor connected to the existing one.
In my opinion that would make corridor placement a lot easier and also cleans up the placement submenu for corridors, hatches and elevators.
Keep up the good work can't wait to play the next released version
kind regards Sparti
