In the steamy jungles of South America, heavily armed extremists are holding innocent civilians prisoner. Little do these terrorists know that real terror is about to land on their front porch! The sound of rotor blades and staccato bursts of gunfire echo through the valleys. Terrorists be warned! Operation Wolf is going to teach you what terror is all about! Operation Wolf consists of six missions, which are displayed on the Operations Map Screen. A mission is completed when all enemy forces are reduced to zero. The current level is completed when you escape from the airport with the prisoners. Your injury level increases when the enemy hits you. The game automatically ends if the injury indicator on the right side of the screen becomes completely red. You can reduce your injury level by getting power drinks.
