A new cinematic trailer has been released
Along with a continued commentary about the story's main themes, that what used to be black and white is now becoming various shades of grey, it also shows what may be new playable characters, including Bane, Robin, Poison Ivy, and Brainiac, while also confirming Darksied as a playable character via pre-order bonus.
A few personal comments:
It's starting to look like Batman won't necessarily be the hero of this story. That would certainly be refreshing.
Are we seriously overloading this with Batman characters again? Give the rest of the DC Universe a chance, would ya?
This may be an Injustice trailer, but for the last third of it, or so, all I could think of was DC Universe Online.
