Codename: ICEMAN is a graphical adventure game made with the SCI engine and published by the American computer game company Sierra On-Line in 1989. The lead designer was Jim Walls, who also created the Police Quest games. Mention of a "Codename: PHOENIX" in Sierra promotional material suggests that ICEMAN was meant to be the first part of a Codename series, but disappointing sales ended the would-be franchise after one game.
