ONE FUTURE ENDS... ANOTHER BEGINS. 3099! From the ashes of the AGE OF HEROES, a new generation of vigilantes, like SPIDER-MAN 2099, NOVA 2099 and RED HULK 2099, emerged in the dystopia that followed to forge a bright, new future -- a future that has come to an end in the face of ABYSSYUS, a horrifying fusion of a KNULL-INFECTED GALACTUS! As the DEVOUR IN BLACK descends upon the world, a deal is struck with the devil -- LITERALLY as MEPHISTO bets the fate of 2099 in a brutal battle of survival, pitting the warriors of 2099 against fan-favorite characters from across the Multiverse -- like AGE OF APOCALYPSE-ERA WOLVERINE, CLAREMONT/BYRNE-ERA CYCLOPS AND MARVEL GIRL, HOUSE OF M-ERA WANDA and so many more -- each battling for their own universe's survival! It's hero against hero in this no-holds-barred war against extinction! But as Marvel's past and present duke it out, only one thing is certain: The future is coming, and it's arriving in the form of... SPIDER-MAN 3099?!
