Avengers: Endgame, which still represents the pinnacle of the Marvel Cinematic Universe for many fans, was released in theaters six years ago today, and Marvel has shared a new 40-second teaser highlighting some of the most memorable moments (and there are a few) from the movie's epic final battle between Earth's Mightiest Heroes and the Man Titan, Thanos.

Among other things, this extended sequence features Captain America lifting Thor's hammer Mjölnir, Iron Man's noble sacrifice, and, of course, the "Portals" scene.

During the climactic battle, Thanos manages to defeat Thor, Iron Man, and Captain America - but Steve Rogers isn't about to stay down. As the Sentinel of Liberty dusts himself off and prepares to fight until his last breath, he hears Sam Wilson's familiar "on your left," and turns around to see Black Panther and the rest of the recently-revived heroes assembling through Doctor Strange and Wong's mystical portals.
