If you ever felt it was weird that security systems couldn't detect breaking and entering then this mod will help. Secure Doors makes it so you cannot barge into every door without repercussions, at least not those locked with a keypad, now doing so will set off the alarms.

I guess this is a difficulty mod because it makes one of the mechanics less exploitable. At the very least it will change the way you think about aggressive entry.
In the future I want to protect some non keypad doors too, like the entrances to offices, for people who like to suffer I guess.
