I am back with plans for a new storyline for DR2. It is set in the city of Moscow, where the UBA is known to reside in. Finally, you will be able to join the UBA, go through their ranks and complete their missions.
I am making the new storyline such that you do not have to complete the Main Missions for the Redchurch Temple to complete the missions for the UBA. However, playing the UBA side first before working for the Redchurch Temple will have a major advantage as your skills would increase over time and you will be able to complete harder missions in the original storyline (e.g. defeating Duney and the Redchurch traitors).
There will be more minor quests as well as major quests to keep yourself occupied for quite a while. White Orbs will be making a comeback; they will be traded for worthwhile skills and services.
More details will come soon.
