Kingdom Come Deliverance patch 1.6 and the free Hardcore Mode DLC are now available for all platforms, and we’ve got the full release notes.

As covered yesterday, the free Hardcore Mode DLC for Warhorse Studios’ story-driven open-world RPG makes the game a lot harder by not allowing autosaving and fast-travel. In addition, the new mode makes combat more realistic as strikes have more realistic impact, and engaging in combat with an experienced warrior without wearing quality armor is very deadly.
