How to unlock the Return to Sender achievement in InFamous 2 - Definitive Guide
Your first opportunity to earn this is during the story mission, “Bertran Takes the Stage”. Near the end of the mission you’ll be chased by a helicopter which you must take down in order to progress. Damage it by shooting lightning at it like any other enemy, and eventually, one of its engines will blow up. It will then laser target you, and then shoot two homing rockets at you. Perform a Shockwave Blast(+) just before the missiles hit you and they'll switch directions and head back to the helicopter. If the missiles connect, you'll not only damage it but also unlock your trophy.
If you missed this opportunity, there are several more opportunities where you will be facing a helicopter such as powered down areas where you can find them patrolling the area.
