ShellShock 2: Blood Trails (PS3) - £14.98 delivered @ Gameplay ! Also available for the Xbox360 at this price.
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.
Taking the first-person war game and turning it on its head, Shellshock 2: Blood Trails places you in a war where fear takes on a whole new meaning.
