Here's What We Know
The video doesn't show any new content, but only reminds that S.T.A.L.K.E.R.2: Heart of Chornobyl is available on PC and Xbox Series, and also shows atmospheric locations of Chernobyl Zone.
It is not known what the developers wanted to say, but if we take into account the title of the video and remember the pre-release promises of GSC Game World, we can assume that gamers were hinted at the imminent appearance of new content. At least two story additions and a lot of free content and technical updates are being prepared for the game.
