The Plasmid Experimentation Era

Lore & Background

As Plasmids became ubiquitous, the dark side of ADAM addiction began to surface. The substance was highly addictive and caused severe psychological deterioration. Users who consumed too much or used it for prolonged periods suffered from hallucinations, paranoia, and violent outbursts. The societal fabric unraveled as citizens turned into 'Splicers,' grotesque mutations of their former selves driven by madness and the insatiable need for more ADAM. What began as a utopian experiment in human evolution devolved into a nightmare where the very technology meant to elevate humanity became its undoing.

In Their Own Story

The air in the laboratory hummed with the electric charge of a thousand broken dreams. Dr. Tenenbaum watched through the reinforced glass as the subject, a former architect named Elias, injected the glowing blue vial directly into his jugular vein. His skin rippled like water disturbed by a stone, muscles swelling and shifting under the surface. 'It is not just power,' he whispered, his voice cracking with static, 'it is freedom.' But within moments, the freedom curdled. Elias's eyes rolled back, revealing only white sclera as he began to scream at shadows that no one else could see. The glass shattered inward, not from force, but from the sheer thermal expansion of a body burning up from the inside out. Tenenbaum knew then that they had not created gods; they had built a cage.

Reader's Guide

The era begins with the isolation and study of Sea Slugs by Dr. Tenenbaum, leading to the synthesis of ADAM. Andrew Ryan immediately greenlights mass production, viewing genetic modification as the ultimate tool for self-determination. Plasmids are released to the public through Fontaine Futuristics and other clinics, causing a boom in personal enhancement. Citizens rapidly adopt these tools for construction, combat, and entertainment, creating a culture obsessed with genetic superiority. The unchecked consumption of ADAM leads to widespread addiction. Users begin suffering from Rapture Syndrome, characterized by hallucinations and violent psychosis. The distinction between citizen and monster blurs as Splicers emerge in the streets. Andrew Ryan attempts to regulate the chaos, but the damage is irreversible. The societal breakdown accelerates, fueling the conflict between Ryan's loyalists and Frank Fontaine's followers, eventually triggering the Rapture Civil War.

Did You Know?

• The original Sea Slugs were harvested from a trench near Rapture, though their specific evolutionary history remains largely undocumented in official records.
• Little Sisters were engineered specifically to harvest ADAM from corpses; the substance itself is produced by the Sea Slugs to facilitate genetic rewriting, rather than being derived from their own genetic material.
• Some Plasmids were designed specifically for industrial use, such as freezing water pipes or melting steel, before being weaponized.
• The psychological effects of ADAM often manifested as a fixation on specific objects or phrases related to the user's past obsessions, professions, or personalities.
