Immense is the word... I submerges you into Batman's world almost completely. I'm only 47% thru and have already fought Ras-a-gul Clayface, Grundy, Penguin, Joker, Freeze... you name a bat villian that wasn't in part 1 and their in this one.
there's a couple I don't recognise. I got Joker, Harlequin, Penguin (my favourite villain ever), Riddler, Cat Woman and Poison Ivy. I think the big green guy might be Poison Ivy's henchman. Bane was it?
As for the thug in black, the fish-bowl, Venom and the Mad hatter, I'm not sure. Also, forgive my poor nicknames for the ones I don't know.
Thanks for letting me know their proper names. Killer Croc! Of course. The Bane I'm thinking of had a mask: [link] But it's clearly the wrong Bane. Hell of a guess for Mad Hatter eh? And no, I didn't notice Scarecrow originally, but I did now I've looked again more carefully.
