mysteriously added new items that fans quickly discovered were part of a new ARG experience and eventually led to a new quest line called The Tarkov Mystery. Now we know that the quest line introduces some new features and can be changed based on how you play.
According to a press release from Battlestate Games, the new Tarkov Mystery quest line features branching possibilities where the decisions you make will impact not only what quests you get to complete, but also whether you complete the quest line successfully or not. This means that you could make it through most of the quest line successfully and then one wrong move could see you fail the whole thing. In turn that could mean you miss out on the exclusive rewards that are being offered to those who complete the quest line, which include an in-game achievement, a unique item that can be displayed in the hall of fame and other bonuses and rewards that are yet to be revealed.
