I have played through the entire game and was able to get a full refund.
The story of Brainiac and the justice league was one of my favourites when it comes from the anime series or the comic's. And the Arkham series is fantastic, but this is a terrible Version of those stories.
The first thing is that most of the game you're playing a shooter with flying tech which makes no sense. The story is very silly with clearly no understanding of how the powers of certain characters work.
The death and story of Batman isn't true to his character following his actions from the Arkham series.
If it was advertised as a shooter alone it would have been good fun, but because the DC universe theme it really doesn't hold its own.
What would have been better if a moral element was added, you the play could choose the outcome of the death's. Added other supervillains who would know how to stop there counterparts.
Wouldn't recommend to buy.
