Update to the update: Oop, it's out now, on December 17th. So, GSC have delivered Stories Untold a day early, but also a day late. Cool. Here's a new trailer, too.
Update: You'll have to wait a bit longer to see what that radio signal's all about. "Due to the last-minute complications, we have to delay the Stories Untold update by a couple of days," GSC have posted alongside a GIF of a dude throwing some medical equipment. The update's now set to arrive this Thursday, December 18th.
Original story follows:
Stalker 2's getting a bunch of new quests just in time for the holidays, with an update dubbed Stories Untold sending you off to investigate a mysterious headache-inducing radio signal when it arrives tomorrow, December 16th. There'll also be a new hub area in the Burnt Forest and a new suppressed rifle for you to fiddle with as you chill by the campfire.
