Ian Sinclair

Ian Sinclair was a scientist working in Mars City Underground. He had special access to the area. As many workers had experienced hallucinations and rumors of Mars City Underground being haunted were circulating, Ian Sinclair was very jumpy in his job. He met the Doomguy while he was on his way to find Doctor Jonathan Ishii. During a short conversation they had, Ian Sinclair discovered that the energy levels in many machines were going out of control. He did not have time to report this, however, because the Demon Invasion soon began. He became a zombie and was later dispatched by the Doomguy.
