About Big-O .Inc
Big-O .Inc is a text-based, incremental management game developed by Maliface neocities. Players step into the role of Emily Harris, a newly-appointed director tasked with overseeing a specialized neurotransmitters production facility. The title focuses heavily on resource management, research progression, subject acquisition, and corporate business relationships within a niche setting.
The experience is designed as a linear kinetic novel tailored precisely to the author's personal tastes, meaning players do not need to stress over branching narrative choices. Operating on a strict desktop requirement, the game runs locally via web browser technology—requiring users to extract the files and open index.html. Mobile devices are entirely unsupported by the developer, and the project explicitly prides itself on being crafted completely without the use of artificial intelligence.
Gameplay and Features
Big-O .Inc combines incremental progression with micro-management mechanics, putting players in control of industrial output and facility operations. The core gameplay loop revolves around balancing neurotransmitter production targets, funding scientific research, and managing human subjects alongside business accounts.

Story and Setting
The narrative follows Emily Harris as she navigates her sudden rise to leadership at the head of a neurotransmitters production facility. Set within a dark, medicalized corporate environment, the story explores mature themes involving BDSM and lesbian relationships. The developer notes that the narrative is largely linear, encouraging players to simply enjoy the ride rather than agonizing over dialogue options or decision trees.
What Makes Big-O .Inc Worth Playing
Big-O .Inc stands out for its uncompromising commitment to a specific creative vision. Because the themes and story cater exclusively to the author's personal preferences, it offers an uncompromisingly focused experience that avoids generic tropes.
