Following on from the events of Avengers: Infinity War, it shows the superheroes who were wiped out by Thanos (Josh Brolin) and those left behind. Before that though, there's loads of new footage to sift through, including one shot that confirms Robert Downey's Jr.'s Tony Stark makes it back to earth.
Avengers: Endgame is in United Kingdom cinemas from 25 April.
Things start off similar to the initial teaser where Tony Stark's floating off in outer space and is sending his last message to Pepper Potts.
"None of us can go back", Carter says.
Chris Evans' Captain America responds: "We'll do, whatever it takes".
"I keep telling everybody to move on", Captain America tells the surviving Avengers.
Then all the major characters take turns saying, "Whatever it takes" as an exciting shot sees them all in white Avengers suits and walking with a goal towards their mission.
Steve's voice is then heard replying Natasha saying "We will, whatever it takes." and a look at Clint Barton (Hawkeye), Scott Lang (Ant-Man), Thor, Nebula and Natasha Romanoff (Black Widow) is shown. However, towards the end of the trailer, there's an unfamiliar face in Avenger series, and if you've watched the trailer, you'd know it's Brie Larson from Captain Marvel who has come to join the Earth's mightiest heroes. "I like this one", Thor tells the rest of the Avengers. However, we were glad that Joe and Anthony Russo ended the trailer on a happy note with the banter between Thor and Captain Marvel.
