Added new loading screens. The update is available after completing the story quest "Hot on the Trail" and before starting the quest "A Minor Incident". ⚠️ WARNING The Zone is ever-changing, and a new update can shift Her structure.
If you’ve chosen to walk the path with modifications, know this: they may not withstand the latest shifts. If you have performance or stability issues following the release of Sealed Truth, we recommend you to disable your mods. For more information on how to correctly uninstall modifications, read the dedicated topic: Thanks for your support and feedback. The Zone keeps improving and evolving. Stay tuned and keep sharing your feedback on our social media.
Please, if you face an unexpected “anomaly”, that is not supposed to be in the game, report it to our Technical Support Center. Our colleagues will take a closer look at it to annihilate and destroy the danger to the Zone. com/hc
