Metal Blade Zone

Metal Blade Zone is a scrapped level that would have appeared on the Sega Saturn cancelled video game, Sonic X-treme. This zone is the only zone of Sonic X-treme that doesn't have official screenshots or any videos. This stage is shown to be a dark sky stage, much like Death Egg Zone. Another stage is confirmed to be a metropolis. Metal Sonic would have been encountered at this stage as a boss.[citation needed]

Metal Blade was going to have three acts: "Nightmare Bridge", "Sewer Shock" and Necropolis".
