If you want to you can just make a title that Konami could make for another Castlevania DS game. If you want you can also add in a story mode.

I think Castlevania Rage of Darkness would be a cool name for a Castlevania DS game.

The story would be 2 foolish teenagers (one of them is a related to the Belmont family) decides it would be fun to enter Dracula's Castle and mess around and get a little thrill of excitment. In the beginning a man runs out of the castle and drops the Vampire Killer. The teens pick it up and enter the castle and find out Dracula's son is the ruler of the castle and must be killed.

Gameplay is 2-D and it's kind of like Dawn of Sorrow and Portrait of Ruin but you find prisoners in the game and they enter your party. A total of 4 prisoners and they can help you with boss battles and getting to areas unreachable. The bad part is you can only have out one partner out at a time.

Make your own!
