The Hero That Heroes Call Achievement in Guardian Heroes

This one is a little hard to get. You just have to beat the game on hard mode with out using a credit. Basically no dying. I suggest using Han, and going down the path in Knightly Nite. Make choices (3,2,5,3,2). The enemies, and that path will be easier. Plus you can use the exploit of quiting back to the main menu if you die/about to die. This will not nullify the achievement. But you will have to replay that stage again.

What you need to do is build up levels early in the game by killing the easy enemies. But when you get to the later stages you will basically just block  the whole time while having the undead warrior going berserk. If you think you will die just quit to the main menu then go back to story mode and restart the stage. I highly recommend you put all of your points to max out Han's health first then strength, later. In the later stages you will just spam block  and column jump. But on the last stage watch out for the barrier priests . They will trap you in a corner and barrier spam you. When you are in the last stage always try to be blocking  in the middle at all times to avoid barrier spam, and try to get in the healing pools so you can be healed. other than that take it slow. Also when using Han use all of his MP by pressing , this will net you free 35-48 exp and can level you up fast.
