From GameWatcher: "It's 1972 and Joe is a janitor at Archon, a research company with a Defense Department contract and a lot of secrets. Joe's crappy day cleaning out wastebaskets gets worse when he discovers an old man dying of a gunshot wound raving about an apocalyptic future, then he gets arrested for the man's murder. After pressing a button the man gave him Joe discovers that it's all true, and the button sends him between 1972 and the desolate far future of 2012. Now Joe has to escape the police station, find the old man's younger self, and prevent the apocalypse. All in a day's work for a janitor."
