Marvel Studios released the final trailer for its latest superhero kaffeeklatsch, Avengers: Infinity War, this morning, and it looks like Thanos is bringing the fight to Earth. Specifically, he’s bringing it to Wakanda, where Black Panther welcomes Cap, Cap’s beard, Black Widow, Iron Man, the Guardians of the Galaxy, Doctor Strange, Spider-Man, and the rest for an epic battle on the African savanna. One question, though—why half of humanity, specifically? Would 48 percent work, or...?

Avengers: Infinity War is set to debut in theaters worldwide on April 27. No need to set an iCal notification; Disney will remind you before then.
