Devilian

Devilian is a 3D hack and slash where you face hordes of demon enemies. Upon the start of the adventure you can choose from three kinds of characters, each with their own special skills and transformations.

The controls in Devilian are standard for the genre, with the virtual stick to move your character around on the left and the attack buttons on the right. Besides your attack button you'll also have a demoniac transformation button, which turns your character into a killing machine from hell.

As you advance through the story in Devilian there are new weapons to unlock that make your hero even more powerful. Obviously you can also unlock new regions on the map to face even more powerful enemies. You can also get help from a friend's character when you're set to carry out a particularly hard mission.

Devilian is a noteworthy action RPG with a smooth combat system, outstanding graphics, and some ideas that are very interesting indeed (like the demon transformation).
