Put the chicken invaders folder in ms0:/PSP/GAME/. The games make heavy use of humor, especially in the form of parodies of Galaxian, Star Wars, Space Invaders and Star Trek. The main theme of the games is a battle between a lone combat spacecraft and a technologically advanced race of space-faring chickens, who are intent on subjugating (and later destroying) Earth.
Chicken Invaders is a remake of the shoot 'em up game Chicken Invaders created by Greek indie developer Konstantinos Prouskas in 1999.
