Teams can now sign up to take part in the CSGO and League of Legends UK Masters Summer 2017 tournaments.
Multiplay has revealed more details on the UK Masters website, including format and prize pools.
Both the League of Legends and CSGO tournaments will each feature a £15,000 prize pool. That's less than the £20,000 offered last year, but still a sizable amount in the UK scene.
There was also a £7,500 Hearthstone UK Masters last year, but no mention of Hearthstone returning for summer 2017 in today's announcement.
The league stages will be streamed live on Twitch from Multiplay's office in Basingstoke, from 7pm to 11pm running Monday to Thursday.
"The format of the tournament remains, with qualifiers leading into a league stage, followed by playoffs and the Grand Finals, live from Insomnia61"
On the tournament format, Multiplay said in a statement: "The format of the tournament remains, with qualifiers leading into a league stage, followed by playoffs and the Grand Finals, live from Insomnia61!
"Eight League of Legends teams will form the league, following four open qualifiers. Counter-Strike will give teams the chance to qualify and join the invited teams in the summer season of UK Masters.
"This season we will be welcoming players from Ireland to compete in the tournament, giving even more teams and players the chance to participate."
Multiplay is also looking for social media volunteers to help with coverage.
Qualifiers begin on May 15th.
