Castlevania: The Adventure ReBirth is a side-scrolling action platform game developed by M2, and released by Konami for the Wii in 2009 as a WiiWare title. It is a remake of the 1989 Game Boy title Castlevania: The Adventure and is the third game in M2's ReBirth series, following Gradius ReBirth and Contra ReBirth. The setting of the game is a century before the original Castlevania title, where the player controls an ancestor of Simon Belmont named Christopher Belmont, who must defeat the vampire Count Dracula.
The Adventure ReBirth consists of six areas that the player has to complete in order to finish the game. Toward the end of each area is a boss the player has to defeat before advancing to the next stage.
The player's main weapon for attacking in-game enemies is a whip, which can upgraded by collecting orbs. The last upgrade lets the player shoot fire from Christopher's whip for a short duration. Unlike the original Adventure title for the Game Boy, there are sub-weapons which are powered with items called hearts. There are five sub-weapons and each has a different use.
