In the year 2033, the most influential and powerful Luciferian Lodges, after centuries of relentless pursuit, finally achieved the unthinkable: they gathered the fifteen manuscripts that make up the Codex Maleficarum, thus completing the feared codex. A text shrouded in the deepest darkness, written in an arcane, indecipherable cryptography that had eluded the brightest scholars of all ages. But these lodges, determined and ruthless, spared no expense, investing vast fortunes in servers, data centers, and computational systems, all with a single purpose: to create an unparalleled artificial intelligence capable of unraveling the secrets of the Codex Maleficarum.

Under the sinister leadership of Count Mortimer, they fulfilled their purpose. Guided by the codex's directives, they performed an ancient ritual that allowed them to open a space-time portal, crossing the boundaries of time to bring forth into this dimension terrible automatons and mechanical creatures, unwavering servants in their mission to subjugate humanity and establish Satan as the only god worthy of worship.

Once the codex's knowledge had been exhausted, the cunning Count Mortimer, always one step ahead, scattered and hid the fifteen manuscripts once again, ensuring that such formidable power would not fall into the wrong hands.

And that is where you come in. You are Soldier MB-001, the first experimental unit equipped with a human brain and metallic alloy, the first member of the Command known as the Metal Brain. Designed to carry out missions of the highest risk, this is your baptism by fire: to recover the fifteen manuscripts and eliminate Count Mortimer, thereby restoring order and world peace.
