Castlevania II: La Venganza de Belmont

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 a unique theme such as air, plant, earth, and crystal, and can be completed in any order, similar to Mega Man . There are large trap rooms in the levels. The game utilizes a password system.
