So, they ate Silver Surfer. I didn't think they'd be able to do that.
Spoiler for those who want it - he actually put up a good fight, but Hulk bit his head off. They all ate him, and found they received some of his cosmic power. Captain America shot energy from his hands. They all agreed that it would make finding food much easier.
At the end, Galactus appeared and the zombies were poised to attack.
Oh, and Black Panther "rescued" Wasp (her head, anyway), and she begged him for some flesh - a finger or something. Ew.
And they ran into a group of uninfected people, but to be honest I read through pretty quickly and didn't recognize if they were supposed to be anyone familiar...
