Blasting Agent: Ultimate Edition

This ability is unlocked by killing 100% of enemies and collecting 100% of gold whilst playing on the Hard Difficulty setting. Once you beat the boss at the end of the level the trophy will pop. Remember to backtrack if needed but don't enter the boss battle door until you have 100% completion.

During this Boss Battle, you take on a snake type enemy that will come out of the ground and arch over you. Once he has arched a few times the snake will begin to move horizontally across the screen. Jump over him and keep firing/attacking. When the life has depleted enough he will start to release butterfly type enemies. These can be a help and a hindrance, as they serve to give you life but also get in the way of attacking the worm. You can use the elevator strips, however I found there to be no point in moving up from the floor.
