Updated to v1.3.1:
Made this feature does not work in Hell because it is almost impossible.
This update contains scripts update, so you will fail to load your save data after updating.
I'm sorry to say this again in short period of time, but please use console commands to revert your game condition.
---------------
Runner's Doom 3 is now version 1.3.
In 1.3, New feature "Random Encounter" is added.
With this feature active, enemies will roam around whole map, so you will encounter enemies at various places where they did not originally exist.
Now you will be chased by resurrecteds while facing unexpected roamers.
This video may explain how this feature works.
This feature adds a lot of enemies in a map, so the degree of difficulty will rise by the result.
If you want to disable this feature, open "monster_default.def" and find "randomencounter_active", then set it to "0".
Note: this feature does not work in Mars City Underground.
