death metal 7 spoiler for anyone interested, it's already out and here's what happened
Spoiler:
Robin King kills everyone and chops off Bruce's Black Lantern Ring. This turns out to be a ploy; Bruce had the ring elsewhere on his body and raises everyone, including RK's troops, into his own army. That's when Alfred shows up. Impliedly, Bruce's army takes RK downPrimarily, Diana beats TBWL. The big concern is that if she wins, the Hands will show up and wipe away everything. TBWL makes one last offer of a paradise for Diana and everyone else if she lets him live. She rejects this and kills him.
The Hands are impressed that Diana would sacrifice everything even unto death, so they offer to restore the Multiverse for an unknown cost. We don't know what it is, but Diana is missing at the end of the story (but everyone knows she's "out there" somewhere).
Big dance party at the end as in Metal #7, but now the villains are invited too.
The Justice League now has a permanent team with the Legion of Doom that exists in a fortress shaped like a black hand ring.
The Multiverse is healing. Future State is a consequence of the new timeline. (Not much to go on there, just that Future State exists.) There's at least one new Earth out there known as "the Elseworld.". Some people previously dead are now alive again, though we don't know who. (Maybe Alfred is among them, since we see Alfred in the black lantern army that Bruce raises to defeat the Robin King.)
Entire issue turns out to have been narrated by Sergeant Rock, who wrote everything in Hawkman's journal in 1943. (I take it that this is a callback to the earliest Metal issues.). The last page is Rock running into battle with the Justice Society.
The Multiverse is restored, including the Dark Multiverse. But a lot new worlds are appearing and Hypertime is mentioned. Basically, they're emphasizing that anything goes now
