Enhanced replays of memorable fights.

"UFC Reloaded" is 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.
