You need to make it so you can have an elevator instead of all those stairs. Also you need to make it so that you can learn that the Apex had created the glitch and they just kept on making themselves along with being able to find the place where they are made. And you can make a robot instead of people to guard you because I would not depend with my life on them because they already kill me.

One of the devs (Omni?) said it is unlikely due to difficulty implementing them. I imagine lots of issues with block detection and alike.
Makes sense, but you never know as development keeps moving on. Plus modders can always take a crack at it. It's not like mod content doesn't become official content.
