The previously North American-only Call of Duty World League (CWL) Las Vegas Open has been altered to include four European teams.
Epsilon, Orbit, Splyce and Team Infused - all featuring UK players - will start in the Infinite Warfare Open Bracket, where they will battle it out to advance and win a share of the $100,000 prize pool.
They join 156 North American teams in the largest ever MLG Call of Duty Open Bracket for competitive Infinite Warfare open play.
The CWL Las Vegas Open takes place from December 16th to 18th at the Mandalay Bay Resort and Casino in Las Vegas.
A post on the Call of Duty World League website said: "While we hope everyone is excited about an even more competitive landscape to kick off the CWL, because of the change from a North America only event to including international teams by invitation to compete, teams who have already purchased a team pass have the opportunity to withdraw from this event and receive a team pass for a future MLG CWL open event taking place in the United States within the next 12 months."
The new CWL season will include four LAN-based competitions as well as a new worldwide Pro LAN league. Players will be able to earn CWL Pro Points during the season to qualify for the CWL Championship in August 2017.
