An exclusive clip from Iron Man 3 debuted at the MTV Movie Awards on Sunday and the extended footage shows more of the shootout between Tony Stark and those trying to kill him and destroy his home. 

The attack on Stark's home is done by helicopters under orders from The Mandarin, Iron Man's nemesis in the film. As the helicopters continue to shoot ammunition toward him, Stark tries to get the Iron Man armor to snap into place as a suit. However, the suit he eventually gets on is just a prototype and Stark has trouble controlling it. He asks Jarvis "where is my flight power," and the artificially intelligent computer responds with "working on it sir. This is a prototype."

Stark tries to hold on to rubble as his home is on the edge of sliding off the mountainside. The Iron Man suit then completely goes offline and has a "system failure," leaving Stark to fend for himself. He begins sliding off of him home - which is already tipped from the explosions - but Spark managing to fire one rocket and destroy a helicopter.
