🏆 EU5 Patcher

Enable Achievements Unconditionally

中文 | English

📖 About

The debate over whether unmodified ironman mode should be required to unlock achievements has been going on for years. While games like Crusader Kings III and Stellaris have adopted a more player-friendly approach, Europa Universalis V has unfortunately taken a step back.

This patcher allows you to:

• Enable all achievements in non-ironman mode.
• Enable all game rules in non-ironman mode.
