While not as fancy as Konami's midnight launch plans – don't expect Hideo Kojima or David Hayter to walk past the launch line you're standing in – GameStop has released a mega-PDF revealing what stores will be holding midnight launches for Metal Gear Solid 4: Guns of the Patriots.
All in all, there are 1,494 locations listed for US stores (including Puerto Rico), so there's a good chance you can find one near you. As always, customers shouldn't plan on showing up at the launch without a pre-order and expect a copy. We hear this game might be a little bit popular.
