Chicken Invaders 3

Chickens. For centuries we have oppressed them, grilling, roasting, stewing, and stuffing them in buns. The time has come for us to pay. Intergalactic chickens are invading Earth, seeking revenge for the oppression of their earthly brethren! It's time for you to fight through 120 waves of chicken invaders for our ancestral right to omelettes. Will you succeed? Will the future of chicken burgers be secure? Or will you end up as part of the menu in a galactic chicken restaurant?
