The Journeyman Project 2: Buried in Time

The second game of the Journeyman Project series finds you traveling through time to clear yourself of a false accusation of altering history. Your future self materializes before you, tells you you've been framed for changing the past and gives you a time travel suit before being arrested by other members of the Temporal Security Agency. Now you must warp back to a variety of time periods and collect the evidence that proves your innocence. (Mobygames.com)
