Xbox UK will be turning London’s Roundhouse venue into an exclusive launch event for Halo 5: Guardians on October 27th.

Partnering with YouTube Gaming, they’ll be streaming Halo 5 for two and a half hours, live from London, at 19:30 pm GMT, and will feature a tournament between the UK’s biggest gaming Youtubers and their fans, a live campaign walkthrough from 343 Industries’ Franchise Development Director, Frank O’Connor. You can watch for free on Youtube Gaming,

As well as that, there will be some fan giveaways, appearances from special, as of yet unnamed guests, and plenty more surprises! If you’re tuning into the UK stream, however, this will start six hours beforehand at 10pm on the 26th, where they can watch, comment, and participate in launch celebrations all around the world. The broadcast will show unique gameplay reveals, celebrity appearances, and live interviews with the 343 Industries dev team.

“‘Halo 5: Guardians’ is the game we have always dreamed of making, and it was important to us that Halo fans in every corner of the world could join us in an epic-scale launch celebration,” says Bonnie Ross, Corporate Vice President, and head of 343 Industries. “Whether they tune into the live broadcast on YouTube or come out and celebrate with us in person at one of our global fan events, we hope Halo Nation will help make ‘Halo 5: Guardians’ the biggest game launch in Xbox history.”
