Change details:
Reworked Rank System
We've adjusted the XP requirements for progression, allowing players to level up and reach new ranks more quickly.
More Variety in Illness Cases
Many players reported receiving the same cases repeatedly. To address this, we have updated the case selection system:
If there are illness cases you have not encountered yet, they will now be prioritized.
All illness cases can appear earlier during progression.
More challenging and advanced cases will also become available much sooner.
Correct Next-Step Display
In some situations, the objective display in the top-right corner did not show the correct next action. This issue has now been resolved.
Improved Progression Information
Players will now receive additional information about rank progression and that this unlocks new illness cases. This information can be viewed in several places, including the tablet.
