I remember the day of the invasion well. The memories still burn deeply, like spicy chicken wings.

They came without warning, squawking menacingly, their ruffled feathers darkening the sun. Invading intergalactic chickens, out to punish humanity for our oppression of their earthly brethren.

I instantly knew what had to be done. I dropped my half-eaten chicken burger and jumped in my cockpit. With a greasy finger I set my lasers to "extra crispy" and blasted off to intercept the fowl invaders.

"Ultimate Omelette" is the title of the fourth episode in the Chicken Invaders series of games. The game puts players at the forefront of a battle against invading intergalactic chickens, bent on revenge against the human race for our oppression of Earth chickens. In this episode, the chickens have constructed a gigantic cannon capable of launching planet-scale eggs against Earth, with the ultimate goal of encrusting humanity in an impenetrable wall made of egg white. Joined by an unlikely ally, players will travel to foreign, unexplored galaxies in an effort to locate and destroy the egg cannon before it reaches Earth.

The enemy repertoire has been significantly broadened, introducing several different kinds of chickens which attack relentlessly in colorful groups and meticulously choreographed formations. The chicken fray is punctuated by fights against boss enemies spanning up to three times the size of the screen. The arsenal at the player's disposal has also been correspondingly extended, with three new weapons and four kinds of supporting satellites providing additional firepower. The player's intergalactic journey is also accentuated by unique fantastic scenarios, such as navigating through a field of gigantic floating feathers, or dodging molten planet chunks during a supernova explosion.
