GSC Game World's 2024 open-world survival shooter STALKER 2 is set to have quite a big 2026, as its first of two planned DLC expansions, Cost of Hope, is scheduled to launch in summer later this year. Officially revealed during the Xbox Partner Preview in late March, the DLC will feature a reignited conflict between two of The Zone's biggest and most well-known factions: Duty and Freedom.
Ahead of the expansion's arrival and at some point in April, however, the devs at GSC are releasing a free content update for the atmospheric FPS titled Sealed Truth — a patch that will expand one of the spookiest locations in the original 2007 STALKER game Shadow of Chernobyl, as well as in the early game of STALKER 2's main questline.
That location is the X-18 Lab, one of the STALKER series' infamously unsettling underground laboratories where The Zone's supernatural phenomena were studied in secret long before the events of the games. These labs typically feature dangerous clusters of anomalies as well as several predatory mutant enemies, making them some of the scariest levels in the franchise.
GSC announced the Sealed Truth update on Monday morning with a teaser image of a previously locked door swung open, noting that "you will be able to open the door to X-18 Lab" and cryptically implying that something is "hiding there in the darkness." Bring a good shotgun and plenty of buckshot, fellow stalkers.

In regards to what we'll find in the unexplored depths of X-18 specifically, it's impossible to say without more information. At the very least, though, I'm expecting several of STALKER 2's deadlier mutants like bloodsuckers, burers, and poltergeists, and potentially even a pseudogiant (one was present in the lab in Shadow of Chernobyl, after all).
Of course, it's also entirely possible we'll encounter a brand new threat of some sort, likely one with relevance to whatever narrative reason we'll have to go deeper into the lab. Sealed Truth's additions may also even tie into the Cost of Hope DLC in some way, though again, we can't say anything for sure right now.
It's also not clear if the expanded X-18 area will be explorable earlier in STALKER 2 or if it's something you'll have to come back to way later after you've progressed far into The Zone and have high-quality gear. If I had to guess, though, I'd say the former is more likely since the rest of X-18 is engaged with in the early game.
I wish we knew more about Sealed Truth's specific release date, but regardless, it's great that we're getting a free content update before Cost of Hope's release later this year. Note that STALKER 2 is also set to get a patch that upgrades its engine to Unreal Engine 5.5.4 before the DLC launches that will improve its performance significantly.
With these updates and an expansion on the way, as well as with the recent addition of Xbox Play Anywhere support, there's never been a better time to return to The Zone or take your first steps inside for the first time. Sadly it's no longer on Xbox Game Pass, but it is nearly 50% off right now with this deal that brings the $59.99 game down to $30.79 at Loaded.
