This one is similar to Rocketmaniac, but you need to do it in Dogfight mode. Put the settings like that:
- 60 minutes level
- 6 frags limit (doesn't work with 5)
- 1 AI in Rookie level
- You with an Attacker plane (more powerful)
- Use the default level (the big greeny plains)
In this level, destroy the first AA you see, you'll get a missile power-up. Then try to kill the enemy with the missiles (it can take some time), the trophy will pop after you'll win the Dogfight.
