Now for the 4 Season of Infamy side missions this what we expect Rocksteady to include in each of them;
Beneath the Surface
Killer Croc is to be fought by Batman in a hand to hand combat boss battle in one of the airships that he crashes down and Batman is to team up with the Red Hood against Croc during Dual Play to beat him
Then after defeating Croc, Batman is to have Jason come help him bring the mutant crocodile to the GCPD Lockup and apoligize to Barbara for kidnapping her as the Arkham Knight and keep her company throughout the rest of the game and wish Batman goodbye once he initiates the Knighrfall Protocol. This mission has to be unlocked after Scarecrow and Riddler are apprehended because we want Batman to have one side mission to team up with the Red Hood in Dual Play and make sure that all the riddles and Riddler Trophies have been solved and collected before Croc brings one of the airships down from the sky
In From the Cold
With Mr. Freeze said to be close to curing Nora at a terrible price, it is unclear if Batman has to take him on in Predator Boss Battle over how the process of his wife's restoration would affect Gotham City or help Freeze cure his wife while making sure everything is stable. Hopefully Nora will be cured even if Victor sacrifices himself to prevent whatever catastrophe his wife's restoration would bring upon Gotham and Baatman would take her to the GCPD to keep her safe.
Wonderland
Batman must break Mad Hatter's control on the cops that he abducted and then bring him to the GCPD Lockup and lock him up with the other supervillains in the Maximum Security Room. It is uncertain if Batman will find him inside the abandoned shopping mall store where the riddle regarding his hats are displayed.
and finally
Shadow War
Batman must stop Ras al Ghul and his assassins from killing all the rioters out on the streets of Central Gotham and to stop him in one final confrontation, Batman must make contact with Azreal either on the rooftops or in the holding cell and team up with him in Dual Play against Ras and his assassins.
After defeating the terrorists, Azreal will wish Batman the best of luck before scouting the city for more of the League of Assassins before returning to the order of Saint Duma to make them answer for what they did to him and Batman would take Ras to the GCPD Lockup for containment in the supervillain holding cell and will be seated in the spot Azreal sits.
Once every expectation in this article is successfully done in each of the 4 side missions, the Season of Infamy DLC will bring a satisfying completion to the main story in Batman Arkham Knight
