The RPG Experience Explained:

Our RPG Experience involves all of the books and unique items you find on our server. RPG stands for Role-Playing Game and "Quests", "Missions, and "Achievements" were created by our team to enhance your Day Z experience! We designed "Quests" to provide a story and direction during your DayZ experience. The books are the key to unlocking our "Quests" which are essentially accessible new discord channels with unique rewards. This experience was created to encourage Role-Playing! Each quest and achievement has varying rewards such as new lore related to the story, treasure maps leading to hidden supply caches, access to new discord channels, and more! Missions are a new feature similar to our quests! You will need to find a unique object or book to initiate a mission, however there will be different additional in-game tasks required to complete.
