Avengers: Endless Wartime written by Warren Ellis, illustrated by Mike McKone, with color art by Jason Keith with Rain Beredo
The Avengers assemble to investigate new drone technology that is being used in a Middle East civil war. The tech has American insignia but is manufactured on the Norwegian island of Skrekklandet. Captain America remembers trying to take out a Nazi experimental (i.e. occult) weapons factory on that island. The factory exploded and sank into the ice. Turns out Thor happened to fight an Asgardian baddie there at the same time, causing the factory to sink and the evil to be buried. But not gone, as it turns out. And the new hybrid Nazi/Asgardian weapons aren't just in the Middle East. S.H.I.E.L.D. has some stored in New Jersey, probably as a fail-safe in case the Avengers go rogue. Thor, Cap, and the rest of the gang investigate and fight to end the threat at home and abroad. Mostly they just fight.
The story is interesting and leads to discussions on the nature of war and heroism. It's not too deep but is certainly more than enough to raise this above the level of a mindless action caper. The art isn't my favorite. The expressions on characters' faces don't always match their actions and words and in general it looks average.
