DC survivors vs DC and Marvel Zombies

A zombified Reed Richards completes the teleporter with some new modifications. He uses the teleporter to take the zombified versions of Thor,Hulk, Sentry, Spiderman, Luke Cage, Ironman, Quicksilver, and Doctor Strange to another universe. But the teleporter takes the group to the DC universe! Starving, the Marvel Zombies immediately befell upon U.S. civillians, heeding the call of other superheroes in an effort to stop the zombies but they are turned as well! Soon the threat of the zombies builds and is too much to handle. Few Survivors (If any) are left alone together in a final last stand against the Marvel and DC zombies. Dear God I hope we win....
So on the DC survivors side, its Superman, Batman with many months of prep following the many months since the marvel zombies came, Martian Manhunter, Wally West, Bart Allen, Kyle Rayner,Krypto, John Steward, Raven,Doctor Fate, and the US military with 500,000 men with 1000 tanks, 250 aircraft, and 30 nucleur bombs.

The zombies are Thor,Hulk, Iron Man, Spider Man, Doctor Strange (Luke Cage was killed by Hal Jordan and Sentry was killed by Superboy), zombified versions of the Justice League,Teen Titans, and others ( I'm not that much of an expert of DC) with dozens minor superheroes with minor powers
