Eidos Interactive will release for this years Christmas, Shellshock II: Blood Trails on XBOX 360, PS3 and PC. The game is an FPS set in Vietman with some “brutal and twisted psychological” aspects.

This is the original game description:
“At the height of the Vietnam War, a covert ops cargo plane carrying a top-secret consignment known only as ‘Whiteknight’ is lost over the deepest, uncharted jungles. Special Ops soldiers are immediately dispatched to the scene to retrieve the top secret shipment and one-by-one they disappear without a trace… until one month later, one of them suddenly walks out of the jungle.

Crazed and deranged, something in the jungle had ripped out his humanity, poisoning his soul. Something in the darkness had driven him mad….and followed him out.”

Lee Singleton, General Manager at Eidos, said that Sellshock 2 seems more like a horror movie than a game. “Survival takes on a new meaning as you fight against all sides of the conflict: your enemy, your allies and the victims… the casualties of Whiteknight, an enemy that ultimately has no side.” said Lee.
That could be the real thing or just PR talk.

Here are some screenshots from the game:
