The base for secret chemical experiments that has significant meaning for the government is under an attack of the terrorists. They have captured the building and you are here to stop them. The task is to attack all of a sudden, so you will have to move as quiet as a mouse. At the beginning of the mission, you will have nothing but a small knife in your hands, so be careful and don’t make noises if you don’t want to get noticed and shot by the enemies. Then the operation will start and get ready to a severe and serious combat.
