GameSpot UK have got a preview of Codename Outbreak from Ukrainian developer GSC Gameworld. Heres a snip:
A first person shooter with a third-person viewing option, Codename Outbreak is set in the near future, just after earth has survived a close encounter with a comet.

Taking advantage of this vulnerability, aliens have landed and are attempting to make our lives a misery by mutating and physically controlling humans and animals.
