The last invasion force is close to the landing strip. After taking out the tanks, do not go after your secondary target. Instead, land your plane and wait for the flak sequence to finish. While sitting on the tarmac, an enemy plane will try to eliminate you. Command your squadron to go into "Defensive" and "Attack" mode. At the conclusion you can switch planes. Note: You only have time for one or two landing attempts before it switches to the "Flak" mode. If this happens, you will have to restart Guadalcanal. If you fail to land your plane, "crash it" before the "Flak" mode begins. You will restart just above the landing strip.
When in a dogfight, hold in the brake to sharpen your turns and thus get the edge on a turning dogfight when trying to outmaneuver your opponent. This is best used with the more maneuverable planes, such as the Gladiator, Zero, Both Hurricanes, and the N1K Shinden.
Once you take the first three pictures of the ships, proceed to the desert. Watch your radio signal when it picks up. You should have the two bars be fully green. When that happens, you can pick up the camp on the radar.
