add a keypad to the door before the most interior reactor door
Why add this:
There is a space that has the appearance of security checkpoint. We would like to make use of that space by putting an additional keypad one more door out from where the current one is. It would make it possible to use it as a better security checkpoint for which shock could use and allows us to keep the reactor secured better during events. It is also out of the for the most part so it won't get in the way of too much.
If I recall correctly, there is also a quest that involves getting into reactor. This feels like an unnecessary change that will make that quest harder for no reason.
