Blood Zero is a single player, top down action/adventure and exploration game released in 2003. Core gameplay consisted of trade off control among four players, and a quite ahead of its time item/upgrade/character/control interface allowing the player easy control over all four characters in combat. The item/upgrade system was very reminiscent of Diablo II, while the gameplay had more of a Legend of Zelda feel.
Settings include haunted mansions, schools, space, hell, grocery stores and ancient valleys. A total of eight playable characters are unlocked throughout the course of the game.
Blood Zero is written in an old version of the Visual Basic runtime and is difficult to get running on modern PCs.
