"UFC Unleashed" features the greatest moments from the Ultimate Fighting Championship's vast library of mixed martial arts footage, including matchups that were previously exclusive to pay-per-view audiences. As opposed to simple highlights, "Unleashed" treats fans to bouts in their entirety, from the opening bell to the knockout, tap out or decision, and some episodes consist of a "best of" compilation featuring one UFC star.

One of the biggest advantages for MMA fans resulting from UFC's programming shift to Fox in 2011 is the mixture of content -- both events and series -- produced for Fox-owned Fuel TV. Some of the best comes in the form of the three-hour, mano-a-mano extravaganza "UFC Reloaded," a re-air of the biggest and most memorable UFC pay-per-view events in history. Of course, the fight results are history, too, but seeing the battles for the first time (or once again) is usually worth the wait, and it's free! The series also features footage that was never shown on the original PPV broadcast.

Enhanced replays of memorable fights.

Features showdowns between contestants of the Ultimate Fighting Championship.
