Marvel’s Avengers : Gameplay video footage leaked!

Although the gameplay is shown behind closed doors to the public during ComicCon, Marvel's Avengers gameplay still managed to be filmed by someone in the crowd! The video shows only a small part of the gameplay, but it's more than satisfying to the fans. The recording lasts for 40 seconds, and shows Thor, it seems at the beginning of the game, fighting enemies on the Golden Gate Bridge. Looks like Tor defeats opponents with his hammer, of course, with lightning and very good sound effects. We see a few combo moves,so as one final, and it's also seen that Thor will have the ability to fly, either at least levitate. Certainly this is a pleasant surprise for the faithful Avengers fans, and the recording is certainly of great quality, so we can see the gameplay nicely. Or maybe this is done on purpose, purely to give everyone the knowledge of what awaits us?
