The biggest video games of the coming year - including the new Star Wars and Call Of Duty - will be showcased together for the first time at the Electronic Entertainment Expo this week.
Virtual reality is also expected to feature heavily among the announcements, and Oculus has already confirmed a partnership with Microsoft's Xbox to stream games from the console when its Rift headset goes on sale early next year.
The event opens with a series of press conferences hosted by the console makers Xbox and PlayStation, along with major studios such as Electronic Arts (EA), the makers of the Fifa franchise and the new Star Wars Battlefront game.
Bethesda, which will introduce a new version of controversial shooting game Doom, is also hosting an event on Sunday evening.
More than 40,000 visitors will then flock to the Los Angeles Convention Centre over four days to try out the latest games for the first time, across around 200 exhibits on show.
