Walk the grim streets of 19th-century London in the notoriously challenging Dr. Jekyll and Mr. Hyde for the NES. This side-scrolling action game presents a unique dual-life mechanic. As the benevolent Dr. Jekyll, you must calmly make your way to your wedding, but the stress and dangers of the city slowly fill your anger meter. Once it's full, you transform into the monstrous Mr. Hyde, unleashing powerful attacks in a dark, demonic version of the world. A truly infamous and bizarre title, this game is a unique and difficult piece of 8-bit history for the most daring retro collectors.
