What if Freeman weren't held in stasis during the portal storm that ravaged the Earth and caught the attention of the Combine? What if Freeman had a chance to prevent the Combine invasion from ever materializing? What if Freeman could reverse mankind's fate? Fate Reversal is a 10-map single-player mod for Half-Life. In the mod you come across a variety of locations (including cities and space stations) instead of spending the entire duration in the confines of Black Mesa research facility.
