I downloaded Dungeon Hunter from the iphone app store several weeks back. I have to say it is a fantastic game! A huge world with a large variety of adventures really makes the game entertaining for a long time. What is really nice is the ability to custimise what type of character you want to play, as well as the skills, abilities and weapons the character uses. This makes the game far more personal and entertaining.
As for the graphics, sound effects, music, fight engine, and overall crafting of the game... well... it is first class the entire way! Check out the attached video below to see for yourself.
Now that I've finished the game (twice), I can't wait for further adventure add-ons, or the sequel. Good Job GameLoft!
