Batman arkham collection

[mot]

In what order does the arkham collection go in and will I have to play origins to understand the plot

[cSg|mc-Hotsauce]

Chronological order of the Arkham series.

Batman: Arkham Origins.
Batman: Arkham Origins Blackgate.
Batman: Assault On Arkham.
Batman: Arkham Asylum.
Batman: Arkham City.
Batman: Arkham Knight.

And no. You don't need to do either Origins game to understand anything.

If you are talking timeline order it is
Arkham Origins
Arkham Knight: A Matter of Family DLC
Arkham Asylum
Arkham City
Arkham Knight: Harley Quinn Story Pack DLC
Arkham Knight

release order is
Asylum>City>Origins>Knight

You don't need to play Origins to understand the plot at all
