Batman: Arkham Knight has joined the ever-growing list of games that have been pushed into 2015. WB Games and Rocksteady softened the blow with a new trailer that teases a "Battle Mode" debuting at E3.

"We just want to make this the best experience that we can, and that takes time," Rocksteady marketing manager Guy Perkins told GameSpot. "We feel that we have an absolutely awesome game in the works, and we want to make it as great as it possibly can be. We just need more time to do that. If we didn't give the team more time to do it, then we would be releasing something that we weren't happy with. We want to make sure we're absolutely nailing it 100 percent."

You can check out the Battle Mode teaser, along with a the stinging "Coming 2015" at the end, in the trailer below.
