Instructions
Press "Start" on the NES controller to open the weapon menu.
Select the "Bubble Lead" weapon. Press "Start" to return to the game.
Avoid the lasers that the alien holograph will shoot at you. Move to the left or right of each laser to avoid it. The lasers have no set patterns, so be prepared to move at all times.
Jump next to the alien holograph, which hovers in the air, and shoot a "Bubble Lead" into it to damage it. Be careful not to touch the alien holograph, as it will damage you. The alien holograph will vanish and reappear in a new location. It will take 10 shots from your "Bubble Lead" to defeat the alien holograph.
