Steel Titans: The Deep Sea Duo

In 2029, mining giant Atlas drilled into the Kermadec Trench and accidentally unleashed a colossal deep-sea monster known as the Abyssal Beast, leaving cities in ruins one after another. Humanity forged heavily armored hunter mechs, relying on two-pilot combat coordination to fight the monsters—and thus the Armor Forge Corps was born.

Jack, a former ace pilot who fled the military after his brother was killed in action, now works as a welder in a scrapyard. But after another Abyssal Beast attack, he is forcibly recalled to duty. His new partner is Maya, a marine biologist with zero combat experience. One bears the trauma of losing a loved one, the other seeks the truth behind the Abyssal Beast outbreaks. Despite their clashing personalities, the mismatched duo gradually builds trust through a series of brutal battles.

Maya's investigation reveals that the Abyssal Beast rampages are no natural disaster—they are man-made catastrophes caused by Atlas deliberately widening cracks in the Earth's crust for profit. Exposing the evidence would cut off the mech corps' material supplies, but staying silent would cost more lives. Jack and Maya resolve to execute a near-suicidal plan: descend ten thousand meters to the ocean floor and seal the trench's rift.

Three mechs push through countless perils as their comrades fall one by one, until only the Iron Tide reaches the abyss. The pair detonate the reactor to weld the rift shut, while command simultaneously exposes all of Atlas's crimes. The Abyssal Beasts retreat into the deep sea, but Jack and Maya remain forever in the dark depths below.
