Castlevania II: Belmont's Revenge

​Castlevania II: Belmont's Revenge ​is the second Castlevania game for the Game Boy.

This game is sometimes referred to as Castlevania: The Adventure II, after the first Castlevania game for the Game Boy, to avoid confusion with the similarly-titled Castlevania II: Simon's Quest. However, that is not the game's official name.

​Gameplay
Unlike the previous Game Boy title, sub-weapons in the form of holy water and axes (or the cross in the Japanese version) are available in the game. There are four initial levels, each taking place in a separate castle with unique theme such as air, plant, earth, and crystal, and can be completed in any order, similar to Mega Man. There are also very large trap rooms in the levels. The game also utilizes a password system.
