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.

This time you will face off against a Shark that attacks in horizontal patterns. You will also be joined in the battle by little squid type enemies. Avoided the Sharks' quick attacks by jumping over/staying under them. Nothing too difficult with this Boss Battle.
