A new promo for Avengers: Infinity War has surfaced, and it poses the ominous question: "Where will you be when it all ends?"

For the various heroes of the Marvel Cinematic Universe, that's an obvious question, as they'll be saving the world. The new promo offers us some new footage, with the most important being a brief glimpse at the reunion of Captain America and Bucky Barnes. Following his two-year rehabilitation, Bucky's looking mighty healthy, even though it's the end of the world.

Backed by the chanting of T'Challa and his fellow Wakandans, we also see Shuri, Thanos, and Okoye have brief moments of action, plus the initial assault of Thanos' forces on Wakanda. There's a clearer look at Tony's new "Bleeding Edge" armor wrapping around his body, Black Widow fighting Proxima Midnight, and Iron Man flying around the destroyed remains of Thanos' home planet, Titan. Finally, Okoye closes things off with saying that an alien invasion isn't what she thought opening her nation's borders would lead to. At best, just a coffee chain.

Avengers: Infinity War comes to theaters April 27. The film stars Robert Downey Jr., Chris Hemsworth, Mark Ruffalo, Chadwick Boseman, Scarlett Johanssen, Chris Evans, Tom Holland, Benedict Cumberbatch, Anthony Mackie, Sebastian Stan, Letitia Wright, Danai Guira, Josh Brolin, and others.
