How to unlock the RDV Homing Missile Expert achievement in G-Force - Definitive Guide
To fire the missles, hold LT until a green reticle appears over an enemy then release to fire. You have a limited supply though, so break open the boxes on the track to get more. You'll get it on the second vehicle level.
Fire L1 to target an enemy and then again to kill the enemy for this trophy. If you don't have this after the last driving mission (there are only two) save in a new spot and load the save that starts the driving mission level and keep doing that until you get this trophy.
