The first paid DLC for S.T.A.L.K.E.R. 2: Heart of Chornobyl is out in the coming months, but GSC Game World has plenty more in store for players. That includes a new content update in April called Sealed Truth, which opens the door to X-18 Lab. “And who knows what’s hiding there in the darkness…” teases the developer.
Of course, fans of Shadow of Chornobyl will recognize the location, though it was called Lab X-18. It served as a testing bed for psychic radiation on various subjects and also designed the Brain Scorcher, a giant radar dish used for mind alteration. If that wasn’t enough, powerful Anomalies can also be discovered. While you can explore parts of it in S.T.A.L.K.E.R. 2, GSC Game World will seemingly reveal much more than players bargained for.
The real question is whether this sets up the events of Cost of Hope, where players explore the Chornobyl Nuclear Power Plant and the Iron Forest. It promises a new storyline that’s “dozens of hours” long, offering “dozens of smaller locations,” various quests, and even a new hub to explore.
While the DLC doesn’t have a concrete release date, it is available this Summer for Xbox Series X/S, PS5, and PC players. Stay tuned for more details on Sealed Truth in the meantime, and check out our review of the base game on PS5.
