Earth Defense Force--EDF--is an arcade shoot 'em up that delivers loads of fun but lacks any other appealing factors.

Aliens attacking earth; giant insects; special forces running around the city on foot (I know, where's the cavalry?)--all good fun.  You play one of the defenders running around the city with your comrades, blowing up alien attackers, and trying to stop the earth from being destroyed.

Gameplay:
The game is fun!  There is little or no realism in this game, it's just plain old arcade-style fun.  You run around with your guy, blasting away at aliens, and demolishing an entire city if you so desire.
Controls are very easy (my six-year old son can play it without a second thought).
The game is family-friendly (maybe an occasional mild expletive).
There are multiple levels to complete and multiple levels of difficulty; higher difficulty levels increase the number of enemies and their aggressiveness.
There is a surprisingly wide variety of weapons to choose from; more weapons become available as you complete levels and find power-ups in the game.

Graphics & Sound:
No complaints in either case.  If you're a hard-core gamer, the graphics of EDF will look average or weak and the sound won't impress--it's no Call of Duty, not even close.  For an arcade shoot 'em up, I was perfectly content with the quality.
The visuals and sound do the job, however, of conveying a city under attack by aliens.  There's nothing that will make you cringe or cover your eyes: no eye sores, no bad textures, no grating noises.

Value:
EDF is an inexpensive game that delivers plenty of arcade action.  If you're looking for a storyline or other compelling gameplay, pass on this one.  It's fun to play co-operative and blast away insects and flying ships; for parents, this is a great alternative to blasting away human enemies.
