Blasting Agent: Ultimate Edition

Simply play through each level on Hard and beat the boss at the end of each one. You do not have to achieve any specific completion percentage to obtain these trophies so take your time and remember to backtrack if needed. Every time you pass through a door your progress will be saved. Don't worry if you die. As long as you have recently been through a door, dying can be a good thing. You do not lose anything by dying, you simply go back to the most recent door and you now have full life again!

For the Hard playthrough, I strongly suggest you use the Character "Sting". Sting is acquired when you beat the game on Normal and is a Martial Arts Character, rather than a Gunner. Once you master the controls of Sting this play through will be a lot easier than playing with the Agent, as When you are using your Punch/Kick combo you are impenetrable to attack.

If you are having trouble completing any of the levels, then see here for a video playlist: LINK
