Here is a link to the first mod for Fear & Hunger since it's release, a Rebalance mod: https://mask.itch.io/fear-hunger-rebalance
This reworks elements of combat and survival in the game, making it so DEF reduces incoming damage, and that Hunger penalties work properly, along with a slew of other minor tweaks. It's a prototype, only tweaking the starting areas monsters, and is not suitable for a full play through at this time.
We really ought to have a Community enabled for the game, so that Mods can be posted in a forum instead of in a comments section.
