Destroy Bees Easily
Here is an easy way to destroy bees: Wait to hear the buzzing sound that notifies you of their arrival. Then wait for them to get very, very close to you (when they lower their altitude to hit you). Use your weapon with star-type ammo to shoot them. You will hit them 99.9% of the time. If you shoot them and they hit you, you will not lose as much health as normal.

Special Gun
On mission 6 there is a special gun you can get. First pick up the nuclear device and then while carrying the device fly up towards the mountains to a steel like drum. Fly over the drum and a special gun will appear and some ammo with it.
