Random Monster Spawns? (Spoilers)

[RoadCrewWorker]

There are many random things in the game, so yes monster encounters is one of them.

If the encounters are generated procedurally, is there a simple way to increase the spawn chance or allow spawns in every area (for a less predictable harder third or fourth playthrough)? I've looked through most config files and haven't seen anything, so i kinda fear it might be compiled into the core binary.
