Chicken Invaders 5: Cluck of the Dark Side introduces one of the newest game mechanics that is purely cosmetic. It allows you to fully customize your spaceship, though upon starting the game, only the base, cockpit, and the engines (inner and outer) are customizable. You can unlock more at the Unlockables, including the Fuselage (paintjob included), Weapon Pods (paintjob also included), Tail Wing (yet another paintjob included), Paint Density and Shininess. Each can be bought for 30 keys, totalling 150.
