Castlevania II: Simon's Quest

From NES Hacker Wiki
Jump to: navigation, search

Castlevania II: Simon's Quest is the sequel to Castlevania. The game play shifts from the original to a platform adventure. You control Simon Belmont, a vampire hunter who uses a whip to fight monsters. You must collect items and enter mansions to find the lost body parts of Dracula. Only then can you resurrect him and vanquish him forever. The game itself is a lot of fun, but it suffered such awful translation problems that it's unplayable without a guide. However, there is an unofficial patch that fixes the dialog.
