The new Avengers: Endgame trailer released by Marvel Studios during the Super Bowl on Sunday shows the remaining Avengers mourning the loss of half of all the life in the universe, but the superheroes are also preparing for a much larger fight. 

The trailer has superheroes like Captain America attending a support group, Iron Man and Nebula repairing -- or perhaps upgrading -- armor, Black Widow practicing at the gun range, and even Hawkeye shows up. It's intense, super intense in fact, punctuated with handclaps that you might say represent Thanos doing the old finger snap.
