okay, I while back, I started studying the Arkham games to see where the side missions could fit, with the story mode, to have it more cohesive. So I finished my study on Batman: Arkham Origins and his DLCs (I'm on Origins Blackgate now and do you know that Toyman is actually dead in the Arkhamverse? He died during the events of Blackgate, so another Superman reference), so here's what I gathered:
First of all, I used this Walktrough
as a basic, then I changed the order of things to put them better with the whole story; another thing of note, for me the perfect beginning is the beginning of the game, but I have a placement for all the tie-in medias taking place before Arkham Origins; and lastly but not least, this isn't a timeline, we already have that thanks to our great
@UltimateWhovian7 this is basically an help (maybe a companion order is the right term) to Mr.
@UltimateWhovian7 in creating a Watching/Playing/Reading Order, so let's begins:
Playing/Watching/Reading Order (Only Main Game):
Batman: Arkham Origins: Chapter 1: "Searching Black Mask in Blackgate" (Chapters name taken from the Batman: Arkham Origins: Official Guide; Chapter ends after the Batcomputer cutscenes)
Batman: Arkham Origins: Chapter 2: "On the Trail of the Penguin" (Until Unlocking Enigma Side Mission)
Batman: Arkham Origins: Side Missions: "Enigma" (From this point on You can go collecting all the collectibles, I won't list where to collect them here, but if you want you can collect them following the walktrough link I gave to you)
Batman: Arkham Origins: Chapter 2: "On the Trail of the Penguin" (Chapter Ends after Leaving The Final Offer)
Batman: Arkham Origins: Side Missions: "Anarky"
Batman: Arkham Origins: Chapter 3: "Investigation on the New Criminal" (Until Leaving the G.C.P.D.)
Batman: Arkham Origins: Side Missions: "The Penguin"
Batman: Arkham Origins: Chapter 3: "Investigation on the New Criminal" (Until Leaving the Sewers)
Batman: Arkham Origins: Side Missions: "Mad Hatter"
Batman: Arkham Origins: Chapter 3: "Investigation on the New Criminal" (Chapter ends with the bank explosion)
Batman: Arkham Origins: Chapter 4: "A Trail to Follow" (Until Leaving the Bank)
Batman: Arkham Origins: Side Missions: "Shiva" (I think that's the best point on where you can start the quest, it is literally 5 steps further the bank and after meeting Shiva, Bats will tell to her he doesn't have time for this, reflecting this point of the plot perfectly, also you could say that Shiva and Deadshot appears on the TV screans of the Royal Hotel, but I also think that's not canon, If didn't happen nothing to them, I see no reason for their absence at the reunion)
Batman: Arkham Origins: Chapter 4: "A Trail to Follow" (Until Unlocking Deadshot Side Mission)
Batman: Arkham Origins: Side Missions: "Deadshot" (I explained Deadshot point with shiva, plus it's an emergency beacon to which Bats will answer Immidiatly, and if you don't think that Bats doesn't deals with both Deadshot and Shiva at this point, just wait for Chapter 6's title)
Batman: Arkham Origins: Chapter 4: "A Trail to Follow" (Chapter Ends after Entering The Royal Hotel)
Batman: Arkham Origins: Chapter 5: "Between the Shadows of the Royal Hotel" (Chapter Ends after defeating Joker)
Batman: Arkham Origins: Chapter 6: "Two Assassin's on the Loose" (Until leaving the Batcave)
Batman: Arkham Origins: Side Missions: "Black Mask" (I left Black Mask here cos I think it isn't something so urgent to having Batman stopping Sionis before getting to Joker, and even then I think doing this during that period of time will slow the narrative incrisenly, so I think doing this here is for the best)
Batman: Arkham Origins: Chapter 6: "Two Assassin's on the Loose" (Until leaving the G.C.P.D.)
Batman: Arkham Origins: Side Missions: "Bird"
Batman: Arkham Origins: Chapter 6: "Two Assassin's on the Loose" (Chapter Ends with the Defeat of Firefly)
