Paradox Interactive has released update 2.0 for Crusader Kings II. The content update, which is free for everyone, adds Ironman Mode, a slew of bug fixes, drops dependance on the Paradox-hosted metaserver, and includes Steam achievements. The new achievements include ones that celebrate the sanctity of medieval marriage.
Until Death Do Us Part – Have your spouse assassinated
Black Widow – As a woman, have three different husbands killed
Keeping it in the Family – Sire a child that has the Inbred trait
The 2.0 patch comes hand-in-hand with the new Sons of Abraham DLC, which focuses on adding more options for the Abrahamic religions like Judaism and Christianity.
