Helicopter Radio
When Act VII, Scene III opens, you attempt to confront Nowak on the balcony of his Costa Rican villa only to have him detonate a bomb that destroys the floor beneath you and sends you falling into the courtyard below. When you regain your senses, you must avoid gunfire from enemy soldiers and survive an attack from a helicopter. Run to your left and take cover behind one of the large stone planters. Concentrate all your fire on the helicopter. Force the pilot to use his radio and your Rainbow support team can triangulate the helicopter's position and blow it from the sky with a surface-to-air missile.
Missile Dodge
Once you hear its pilot radio for help, the helicopter stops firing, warning that a missile is on its way. Stand back from your cover and sprint away from the incoming missile. Take cover behind another planter on the right side of the tennis court's fence. Engage the ground forces from this position and then prepare for another missile assault. This time, sprint to the left to find cover. Whenever you hear the helicopter stop firing its guns, know it's preparing to fire a missile. Listen for this audible clue to tell you when to get ready to run.
Shack
Kill any ground forces in your way and run across the tennis court and through a hole in the fence. Sprint to the nearby shack and take cover. Continue to gun down the ground forces and wait for your support team to eliminate the helicopter. As soon as the helicopter explodes, exit the shack and prepare to confront Nowak.
Nowak
After surviving the helicopter and ground forces, you won't have much trouble with Nowak. Listen to him talk for a moment, but always keep your gun poised. When Nowak draws his weapon, pump a few shots into his chest to complete your final mission. A cut scene plays showing the rest of your team gathering around Nowak's body. A closing dialogue plays and credits roll.
