The UK qualifiers for the Call of Duty XP Black Ops tournament take place next Sunday, 7th August in London.
Register your Xbox 360 Call of Duty: Black Ops team on the COD XP website to take part.
On the day, 128 competitors will be whittled down to four at London's Sound in Leicester Square.
That victorious quartet will be flown, all expenses paid, to the Call of Duty XP event in Los Angeles in September.
The final showdown between 31 teams will take place on 3rd September. The star prize? $400,000.
You'll be able to watch a video stream of the qualifiers on the Multiplay website after the event.
