Brazookas is an unreleased and unfinished title for the Sega Genesis. It's known as a prototype, or beta version (v.0.1). Details about the game's mechanics and its intended story are scarce, as the game never saw official distribution.  Its appearance in Brazil suggests a regional development or testing, but the limited information means much of the game's nature remains unknown.  Its 'Unl' designation might signify an unlocked version.
