Hint: Flak Cannon:
The Flak Cannon works well at close range. Fire it at the first group of landing craft then use your pistol for the tanks at long range.

Hint: Destroying motherships:
Try landing on them and give them an up close and personal look at your Flak Cannon.
Garrett Martin.

Land on the motherships and shoot the sides and back with your Assault Cannon/Flak Gun. Then, fly off and use missiles on the sides and belly.

This trick is very useful on last actual fighting level. Fly up to the ship and land on it. Face the front of the ship. Go to the tip, and on both sides will be guns. Use a Trident to destroy them. After you destroy the two guns use a Trident or Gauss gun and shoot the top part of the front two or three times to destroy the enter ship.

Hint: Eliminate fighter launches:
Land on top of enemy drop-ships and destroy the hanger bays to eliminate the constant fighter launches.

Hint: Crashing enemy ships:
In mountainous terrain, land next to and remain close to a high cliff wall when enemy bombers or fighters are near and wait. They will crash into the mountains.

Hint: Infiltration radar:
If you do not want to be seen by radar, fly over them as high as you can.

Hint: Exploding dinosaurs:
In Zone One, if you go behind the weapons armory there are dinosaurs that will explode if shoot them with anything besides the Vulcan Cannons or the Machine Pistols. If you do, they will just die.

Hint: Custom soundtrack:
Go to the options menu at the main screen. If you have already created your own soundtrack on the hard drive, you can listen to it during the missions.
