Along with that, they're showing off a new Wave 23 preview mini in the form of the Nightwing Swarm.

No, this is not some cross-over event with DC where they clone a bunch of Batman's sidekick and let them loose in the Jwar Isles... though that would be pretty cool...
Instead, this is a bat swarm with some extra bite (pun somewhat intended). So now your Giant Cave Bat for Savage Wave can have some little friends to play with.
