Patch 1.29c - Hellish Difficulty Level/Ultra Realism

If you feel that the game is too easy and too unrealistic for your character, the patch 1.29c allows you to try the hellish and very realistic difficulty level, above just merely realistic/harsh.

Would you like your character to heal from minor wounds for a week, if not longer, to feel the realism of your in-game pain? (or, what is more likely, to just die?)

Patch 1.29c, while it's not mandatory, gives you such an option.

Yes, it's still possible to complete the game, if you are wise and lucky and patient- but truly hellish.
