Taking place 500 years in the future, the game tells the story of Lu Chen, a sinister world overlord more commonly known as the SovKhan, who rules the Earth from a massive complex called Megacity S1-9. The only resistance to the SovKhan is from an ancient order of warriors known only as the Guardians. The SovKhan's army is nearly invincible as it is, and it is growing by the day, his most powerful units being 60-foot-tall humanoid robots called "Slaves". The Slaves themselves are grown from a combination of artificially created cybernetic embryos and a mysterious compound called NTR95879, referred to as "dark matter" by the Guardians. Now the Guardians' only hope of overthrowing the SovKhan and his cybernetic army lies in a single captured Slave unit, which will have the mind of a specially trained Guardian agent permanently downloaded into it. The game follows "Slave Zero" as he wages war against the SovKhan's forces throughout every part of Megacity S1-9.

In June 2022, Ziggurat Interactive (owners of franchises such as BloodRayne, KKnD, Uprising, among others) announced a prequel to the original Slave Zero. Titled Slave Zero X, the game's genre was described as a side-scrolling hack-and-slash as opposed to the original game's third-person shooter premise. It was also announced that SungWon Cho and Anjali Kunapaneni were added to the game's cast. Slave Zero X was released on February 21, 2024 for the PlayStation 5, Xbox Series, PlayStation 4, Xbox One, Nintendo Switch, and PC. It tells the story of Shou, a member of the Guardians resistance group, who steals the group's salvaged Slave Bio-Armor "X" and sets out to slay the tyrannical SovKhan and his Five Calamities. In addition to Slave Zero X, Ziggurat partnered with Ironwood Software and Poppy Works for Slave Zero X: Episode Enyo, a total conversion for the first-person shooter game Quake, which features Enyo, one of the antagonists of Slave Zero X as the playable character. It was confirmed to be part of the series' canon as it took place prior to the events of Slave Zero X.
