I am the terror that... wait, that's Darkwing Duck. Hmm, that'd be an interesting addition to the Batman Miniatures Game from Knight Models. Not like it'd ever happen, but it's a nice thought. In the meantime, though, there are several new releases available for the game. These sets focus on the Arkham Knight versions of the characters.
This time around we get a new version of Batman (because, of course!), Robin, a Harley Quinn gang, Killer Frost, some generic Arkham Asylum Inmates, and a set of 10 bases. Ok, so the bases aren't necessarily from the Arkham Knights game, but they're decent-looking bases.
You can pick these up over in the Knight Models webshop.
