Dark Arkham Asylum sequel Batman: Arkham City will be playable at this year's Eurogamer Expo.
Full day tickets for Saturday have now completely sold out, although discounted afternoon-only entry (2pm-7pm) is still available.
Batman: Arkham City isn't out until October - it's one of the many huge titles gamers will be able to get their hands on at Eurogamer Expo 2011 before they're out on shop shelves.
We've already announced Battlefield 3, Mass Effect 3, Uncharted 3, FIFA 12, Rage, Assassin's Creed: Revelations and many more.
Eurogamer Expo is Britain's biggest and best games event. It runs from 22nd-25th September at London's massive Earl's Court One.
