Earth Defense Force 2 Portable being released as two-pack in Japan

D3 Publisher is including an unusual, but sensible bonus with a limited edition of Earth Defense Force 2 Portable: a second copy of Earth Defense Force 2 Portable. The first print run of the PSP remake will be available as the "Double Enlistment Pack," containing two UMD copies of the game — in full retail packaging — bundled together for ¥6,279 ($76), a significant discount over buying two ¥5,040 ($61) copies individually. It'll be out in Japan April 7.

This is a great way to get a co-op game into the hands of a population that already has a bunch of PSPs and a taste for multiplayer on that system, thanks to Monster Hunter.
