Team EnVyUS from America have been crowned Call of Duty: Black Ops III World League Champions.
They beat British team Splyce to win the $800,000 (£600,000) prize in LA.
It was the first time a team from Britain made it to the final but they were outclassed by their US opponents.
The four-day competition was held in front of a live audience at the Forum in Inglewood, California, and was streamed online via Twitch, MLG.TV, YouTube and through the game itself.
“Winning this event, in front of this crowd is a dream come true,” said Jordan “JKAP” Kaplan, Team EnVyUs team captain.
“The energy, the tension, and the competition were all amazing. This is a moment that I will remember for the rest of my life.”
The competition was launched in 2011, with teams from the US usually dominating.
But this year two teams from Europe made it to the final day of gaming with FAB, a team made up of players from Germany and the UK, joining Splyce in the semi-final.
It marks a big improvement since last year when all European teams were knocked out on day one.
Splyce took home $250,000 (£187,000) for coming second but no-one left empty handed.
All 32 teams will at least get $15,000 (£11,300) for taking part.
The Call of Duty Championship marks the end of the first year of the Call of Duty World League, which publisher Activision created last year to make the most of the growing eSports market.
