Set during the Vietnam War like its predecessor Shellshock: Nam '67, Shellshock 2 features a storyline that has the U.S. losing a covert ops cargo plane in the jungle. Carrying something known as "Whiteknight", it polutes and corrupts everyone who comes in contact with it.

"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 Eidos Game Studios general manager Lee Singleton.

The "brutal and twisted psychological first person shooter" is in development at Rebellion, developer of games such as Alien Vs Predator, Rogue Trooper and Sniper Elite. It is currently planned for a Christmas release.
