Project IGI: I’m Going In, released in 2000 by Innerloop Studios, remains a cult classic in the tactical first-person shooter genre. Unlike many modern games that offer a chapter select from the start, Project IGI enforces a strict linear progression: you cannot play Mission 2 without completing Mission 1, nor can you jump to the final confrontation at the Doukhounor radar station without fighting through all 14 preceding missions. For many players—especially those returning to the game after years, or those stuck on a notoriously difficult level like Mission 7 (“Infiltration”) or Mission 11 (“Echoes”)—the desire to unlock all missions instantly is powerful. This essay provides a useful, practical guide to understanding the game’s save structure, legitimate ways to unlock missions, and the most reliable methods for bypassing the linear lock.
