If you are a fan of the S.T.A.L.K.E.R. games, you should know that some of the original developers are creating a successor called Survarium. The game is a free-to-play MMOFPS set in the near future and focuses on the aftermath of a massive ecological catastrophe on Earth, the reasons behind which are only vaguely known.
After the page break you can find 3 new screenshots of the upcoming game. Check out the official survarium site for more information.
