ESL and AT&T have partnered to launch a new amateur mobile gaming league.
The ESL Mobile Open begins its first season March 18 and offers a prize pool of $330,000.
Anyone can enter the tournaments, which will focus on three titles: PlayerUnknown's Battlegrounds, Clash of Clans and Asphalt 9: Legends.
"A first in the industry, ESL Mobile Open was developed to provide anyone with a phone access to compete at the highest levels with both established and emerging mobile esports titles," said Yvette Martinez-Rea, chief executive officer at ESL Gaming North America, in a statement released Monday.
AT&T, which has been an ESL gaming sponsor since June, has the second-largest U.S. wireless audience, according to Bloomberg.
