About C15: Horror
C15: Horror is a horror game about Alexander Grozov, an unemployed man who agrees to take part in a paid experiment. The scientist Rage Sinner, a neuroscientist researching quantum mechanics, has created a serum that can move a subject’s consciousness into an alternate reality. After arriving at Rage’s home and seeing equipment that reminds him of a drug lab, Alexander undergoes the experiment. You help him escape, and your actions determine his fate across three possible endings.
The experiment
Rage advertises for volunteers to test the serum on living people. Alexander, who has been out of work and needs money, responds. The experiment sends him into another world, where what happens next depends on your choices.
