This trophy is titled "
Revelations" and it's an unmissable story based trophy for Episode 5, Chapter 2.
Chapter Walkthrough:
*** Spoiler - click to reveal ***Penguin Route:
With Batman's tech all but disabled, he pulls out a cellphone and makes a call to Alfred, but is interrupted by another Penguin drone. Talk with the Penguin and then disable the drone. Afterwards, tap into its communications to hear about his plans at Cobblepot Park for Batman. Batman and Alfred will discuss this and plan to stop Oswald as Bruce Wayne.
At Cobblepott Park, the police get ambushed by the Penguin and suffer heavily. Convince Lt. Gordon to let Bruce attempt to distract Oswald as Gordon destroys the drone transmitter within the park. Talk with Oswald as Gordon makes his way around behind him. Like most of the options, not most just lead to one or two different lines of dialogue until Oswald decides to kill Bruce and the drone surround him. The way the transmitter is destroyed differs depending on the choice made. Gordon will destroy the transmitter if you select to tell him his mother belonged in Arkham. If you select that they're not done talking, he'll spot Gordon, attacking him, and Bruce will have to destroy the transmitter himself. With Oswald out of commission, Gordon will thank Bruce and they'll part ways.
Harvey Dent Route:
Batman & Lt. Gordon run through the hallways of the GCPD. Perform some quick time events to save a group of officers from Dent's security forces. A wounded officer will inform Gordon that the commissioner is defending the lobby, but can't hold out much longer. In the lobby, Grogan falls to the floor and is about to be executed when Batman saves him and then Montoya. Defeat the surrounding Enforcers only to have Grogan save Batman, but get killed in the process. Comfort Gordon about Grogan and then an officer will radio that Dent is at the ruins of Wayne Manor, executing hostages while waiting for Bruce Wayne to show up.
Batman will call Alfred to check on him and they'll formulate a plan to confront Harvey as Bruce Wayne. A flashback occurs to Bruce and Harvey discussing Dent running for Mayor, then the scene transitions to the ruins of Wayne Manor. Bruce will walk in and confront Dent. Continuously appeal to Harvey while Alfred brings the drones online to stop Dent's Enforcers. Eventually Harvey will make a coin flip and Bruce will grab it giving a choice to throw the coin or pocket it. Both options will stop him, but have different scenes of Dent being defeated. The GCPD will be on-scene, leading Harvey away. Jack Ryder will let Bruce know that he's a hero and Gotham will hear about his actions. The Child of Arkham hostage will attack Bruce and get shot by the GCPD officers. Before dying, he'll tell Bruce that Lady Arkham isn't done.
Chapter End (both routes):
Bruce will be at the Batcave talking with Alfred about how shutting down the computer saved the Batcave, but wrecked their systems. Alfred will voice his concerns about Bruce's wellbeing while feeling guilty for everything. Both Bruce and Alfred will compose themselves and focus on stopping Lady Arkham and the Children of Arkham. At the Batcomputer, you can log into Wayne Enterprises or look at the file on Lady Arkham. Logging into Wayne Enterprises has Bruce investigating Oswald's actions while he was in charge.
Look at each folder and then back out of the Wayne Enterprises system to look at the Lady Arkham file.
Investigate each of the options, the Gazette twice, to unlock more options. Check on the last two options and the trophy will unlock during the subsequent scene discussing Wayne Tech.
