Electronic Arts will show Mass Effect 3 and Need for Speed: The Run at this year's Eurogamer Expo in September.
The AAA titles join Battlefield 3, Star Wars: The Old Republic and FIFA 12 at the event.
"We're thrilled that EA has expanded its showcase to include Mass Effect 3 and Need for Speed: The Run, two of the biggest games due out in the next 12 months," said Rupert Loman, managing director of Eurogamer. "Together with the likes of Battlefield 3 they represent an incredibly strong line up at the Eurogamer Expo."
Konami, Namco Bandai and id Software will also be supporting the event, and Sega will present the Eurogamer Expo Indie Arcade.
The Eurogamer Expo is predicted to attract around 30,000 attendees to London's Earls Court between September 22 - 25 and is the only expo of its size in the UK. GamesIndustry.biz will also be holding a career fair at the show.
