War, they say, is hell. It's noisy, disorientating, brutal and confusing - an assault on the senses. Yet in many games, this atmosphere of extreme danger is a thin veneer hiding an essentially linear narrative. A path has already been chosen and little thought is required besides how to kill the enemy in front of you. Operation Flashpoint is different though. Its limited number of scripted events and open gameplay translate into an atmosphere that at times, is unrivalled.
