ThE Napalm Gun + Unlock it's upgrade ability
To get the Napalm Gun, all you have to do is complete the first level WITHOUT SHOOTING ANYTHING EXECPT THE BOSS OF THE LEVEL. However, you DO have to complete one more task before it stays with you for the whole game: you MUST complete level 2 WITHOUT DYING. If you can complete level 2 without dying, the congratulate yourself on a job well done; you now have the most powerful weapon in the game. I have recently learned that you can also unlock the ability to upgrade the Napalm Gun. Clear the second level WITHOT HITTING or SHOOTING ANYHTING execpt the boss. If you can accomplish this difficult task, you can now upgrade the Napalm Gun. At Level 3 the fireballs bounce off walls.
