Excited for Batman: Arkham Asylum? Well, you should be, because its about the only good Blu-Ray game coming out this August. Batman will be sneaking and brawling his way through all of Arkham on the 25th, and us lucky PS3 owners will even get some exclusive content, allowing us to play as the nefarious Joker in the Challenge Maps. Not only that, but the demo releases on Friday (oddly enough), so you'll even get to do some batting around three whole weeks before the game releases.

Exciting, right? We're going completely batty. Just to tease everyone, nearly twelve minutes of the game has been posted over on dailymotion.com, so check it out after the break. Us? We're going to bed, we can't stand all this excitement, good knight.
