A never-before -seen-footage from "Avengers: Age of Ultron" was revealed during the Marvel's Hall H presentation at the San Diego Comic-Con 2014 on Saturday. The cast took to the stage, including newcomers Elizabeth Olsen and Aaron Taylor-Johnson. Scarlett Johansson missed the event due to her pregnancy. Although they didn't reveal any details about the much-anticipated sequel, the footage was already enough to excite fans, as it revealed the death of the avengers and even Ultron's form.

As previously reported by IBTimes, the first 20 minutes of "Avengers: Age of Ultron" involves the team's celebratory party at the new Avengers Tower after they have defeated Von Strucker in his Hydra outpost. The footage picks up from that scene where the heroes attempt to pick up Thor's hammer, the Mjolnir. According to slashfilm, Tony Stark took the first attempt in exchange for ruling Asgard.

"If I lift it do I get to rule Asgard?" he asks Thor, to which Thor said yes. But of course Stark fails even after putting on Iron Man's glove. Hawkeye and Bruce Banner also tried and failed. Capt. America manages to just budge it a little which had Thor worried for a bit. After many failed attempts Thor claimed, "You're all not worthy."

Just then a shriek echoed then a voice says, "You're all not worthy." Then Ultron enters to the surprise of the Avengers. Slashfilm described Ultron as a zombie-like, beat-up metal being since as Screenrant added, he is still half-made. His silver plating still messily forms part of his upper torso armour.

"How could you be worthy? You are all killers. You want to protect the world but you don't want it to change. There's only one path to peace... your extinction," he tells the Avengers. Then his legion of robots comes invading the tower. Thor picks up his hammer ready for battle. Then the footage changes to reveal a mixture of different scenes taken from "Avengers: Age of Ultron."

People are seen running away from an immense battle while Ultron's voiceover says, "I had a vision ... the whole world screaming for mercy. Everyone tangled in strings." Then Bruce Banner is seen looking ill as Ultron's voiceover continues with "Strinnnngs." Then the scene changes again to reveal Banner now in the snow.

Then Hawkeye and the other Avengers are seen helping people escape. There's a shot of a hospital and Scarlet Witch is seen on a bus. Then Banner is seen again but this time as The Hulk, smashing a tank.

Then Tony Stark's voice over, "It's the end. The end of the path I started us on." In which Black Widow adds, "Nothing lasts forever."

Scene changes to feature Iron Man in his new armour the Hulkbuster. He is flying over what looks like a prison according to slashfilm, firing at soldiers. Then he and Hulk engage in a fight. Hulk throws a large car at Iron Man then lunges forward, pushing the car farther into the Hulkbuster. Then there's a scene of Black Widow riding the new electric Harley and Quicksilver also speeding around as the battle continues with more explosions.

Then Ultron appears, this time in his full 8-foot full metallic glory, no longer the skeleton that attacked the Avengers Tower. As he says "There are no strings on me" the Avengers "A" logo pans out on the screen as it forms from his clenched fist.

The footage of "Avengers: Age of Ultron" ended revealing Capt. America's shield torn in half. Then Tony Stark is seen standing on a vast field looking down at what seems like the dead bodies of the other Avengers, all sprawled at what slashfilm hinted may be Thanos' tomb.
