Developer Hi-Rez is feeling mighty generous right now, as they are celebrating the 20th anniversary of the Tribes series by giving away all of the games in the series for free.
These games date back all the way to 1994 with Earthsiege and goes all the way up to 2012 with Tribes Ascend. In total were are looking at 7 games that you can download for free right now.
