The Esports Fight League is where the very best competitive EA Sports UFC 4 players fight in weekly events, to see who is the best in the world. Both Xbox and PS4 have their own rankings in which a champion must be crowned, but how long can they reign? The ESFL Network also hosts smaller affiliate leagues; The UFL, The IXC, and Primetime MMA. These leagues are for upcoming prospects to show off their skills and climb the ranks to earn a spot in the ESFL. Headquarters: United States
