If you haven’t had a chance to play ‘Earth Defense Force 2017′ (or simply ‘EDF’), then you’ve been missing out on one of the most entertaining co-op shooters on the Xbox 360. In Japan, the game was a 2006 release for the 360. It hit the States in March of 2007. It’s an early title for the system, and that shows in every way possible. The achievements are awful and don’t get awarded to the second player, the controls are lacking, and it doesn’t look anything like current games on the system, but it's some of the most fun you'll have in co-op.
