Batman: Arkham City will be available a day early. The first 100 customers who pre-purchase a copy of the game through the store's "Personal Shopping Department" (starting now, we guess?), will receive a ticket reserving their copy, and can have their game autographed by Jim Lee (co-publisher at DC Entertainment), Kevin Conroy (the voice of Batman) and Sefton Hill (B:AC Game Director from Rocksteady Studios) at the event.
The other 400 copies will be available for purchase at the event, which officially starts at 4PM, but who knows when people start lining up? The event will include photo ops with actors dressed up as Batman and Catwoman, and game demos.
Obviously, keep your eye on the prize. You could get Batman: Arkham City a day before everyone else, or those with Amazon Prime who longingly stare out the window for any glimpse of the UPS man.
