Star Raiders

This is pretty easy. When you start a mission, it will tell you if there's a Zylon Frigate or Cruiser you need to destroy. The majority of missions are untimed, so you can do this on virtually any mission that features a Frigate or Cruiser. It's generally best just to do this the first time you run across one of these ships just to get it out of the way.

For a Frigate or Cruiser, are two different things you can target on it, which I will call turrets and generators. Turrets, obviously, are guns that shoot at you. Generators are large green cylinders that rise up from the surface of the ship for a brief period of time. Here is what one looks like:



Only when the glowing cylinder portion of the generator is exposed (as seen in the pic) can you damage and destroy it. When it retracts, you have to wait about 3-5 seconds for it to rise up again. In order to get this trophy, you need to destroy all the generators on the ship without destroying any of the turrets.

Frigates have 8 generators. Cruisers have 12 generators.

All you need to do is fly close to the ship (within 1-2 km of the targets) and change to Assault Mode. In Assault Mode you'll just hover there and you can easily target the generators and shoot them with your light weapon when they are exposed. Use to cycle through targets and then to ensure that you are locked onto a generator. Just be careful once you destroy a generator that you don't accidentally lock onto a turret and keep firing (you don't want to destroy any of those).

Move around the ship and methodically take out all the generators. You'll move slowly and will be a sitting duck for turrets and fighters, but it's no big deal as you respawn forever. Take your time and the trophy will soon be yours. If you're having trouble, kill some of the other Zylon Turrets and Fighters that are scattered around the level first.
