Guide Era through monster-infested streets, recruit conflicted former biotech staff, collect evidence of Stardust’s illegal T-7 Symbiont experiments, and race to find the antidote before corporate mercenaries purge the last surviving residents of Blackrock City.
Symbiont Zero-Type Core Story & Setting
1. Set in the year 2079, Stardust Biotech Corporation secretly launched the T-7 Symbiont project under the guise of rare disease treatment, fusing human cells with extraterrestrial genetic material to create super soldiers. The experiment spiraled out of control, turning infected humans into violent, distorted monsters known as Distortions.
2. To cover up the disaster, the corporation locked down the entire Blackrock City where the research base is located, and deployed mercenary teams to eliminate all surviving residents. Era Lane’s younger sister Lia, the only researcher who knew the formula for the outbreak antidote, went missing after sending a distress signal right before the lockdown.
3. The game features a branching narrative system where every player choice impacts story progression, ally survival rates and final endings, with multiple hidden routes to uncover the full truth behind the T-7 experiment.
Symbiont Zero-Type Playable & Support Characters
1. The protagonist Era Lane is a 24-year-old ex-special sharpshooter formerly employed by Stardust Biotech’s security department. She was framed and expelled three years prior for refusing to carry out the order to dispose of experimental subjects, and has been investigating the company’s illegal experiments ever since.
2. Key recruitable allies include 20-year-old core T-7 researcher Lia Lane, who is imprisoned in the underground lab and holds all key evidence of the experiment; gentle but guilt-ridden junior researcher Mia, who holds fragmented experiment logs that reveal the project’s dark secrets; and Haley, a remaining hospital nurse who knows how to temporarily suppress early-stage T-7 infection.
3. Antagonists include Marcus Kane, the 51-year-old obsessive project director who will stop at nothing to seize Lia’s confidential data to cover up his crimes, and Logan, the 34-year-old mercenary captain tasked with stopping Era, who gradually grows conflicted as he learns the truth about the corporation’s actions.
