This year's Insomnia festival, the i47, will make the shift from Counter-Strike: Source to Counter-Strike: Global Offensive. Signups to the tournament have already begun. So, for your shot at £4,000 you better follow the instructions laid out below.
Buy a ticket from here - there's a whole slew on offer: Bring Your Own Computer weekend and day passes, Turn Up and Play passes that allow you to use one of the machines provided, as well as spectator tickets. Once that's done you'll be able to sign up and secure your place at the tourney.
It's a sign of confidence in the new iteration of Counter-Strike that the tournaments are adopting it as the cannon shooter. There certainly aren't many tournaments running games of Condition Zero, for instance.
The iSeries takes place over the 30th November to the 3rd December.
