They had it for $9 at my BB.
BTW, the game is great; but it's NOT a "Contra" style arcade game. It's actually closer to, dunno, "move your character ala Resident Evil to the place you want her, and then dodge ala Dance Dance Revolution". Your character can NOT make any quick movements; you put her in a place, and work to duck in and out of cover while firing. It's a 100% timing game; actually *moving* the character is a chore, since it's this wild action game... with the Resident Evil control scheme.
Fun for what it is, even though it's obvious the game was rushed and has pretty much zero interface.
