Chikyuu Boueigun 2 Portable

Also known as Earth Defense Force 2, this game takes place 3 months after the Invaders war. The mutations started in England. Upon receiving the SOS call from London, the hero flew in to investigate. Instead of the elegant city, all he sees are ruins and large insects rampaging what remains of the buildings. Join the EDF force, pick up your firearms and battle the monsters and aliens that infest the planet.
