Australian zombie-haters have it even better: NeoGAFfer untoldhero (an accurate name if ever there was one) found a convincingly official-looking retail listing for a "Bang Bang Box" bundle containing the full Collector's Edition of the game, with the special sleeve and the comic book, as well as two Hand Cannons, for $89 AUD ($59 USD). That price has got to be a mistake. We've got a picture after the break of the heartbreakingly awesome package.
Sadly, we've seen nothing about the Hand Cannon in the US. We fear that Sega's deal with Venom doesn't extend out of PAL territories.
