The chickens are back with their usual plans of world domination, and this time they're taking over Christmas! Forget all about Christmas Turkey and step up to Christmas Chicken in this festive edition of Chicken Invaders 2. Advance through waves of invading chickens, avoiding falling eggs and collecting power-ups to boost your spaceship's firepower. Fast-paced arcade action for one or two players. In the first chapter of the Chicken Invaders saga, you defended earth against an invasion of intergalactic chickens seeking revenge for the oppression of their earthly brethren. However, as you were clearing out the last of the chicken invaders and were looking forward to a double chicken burger special at the space burger bar, the true scale of the problem became apparent: the first invasion was simply a precursor to the chicken's main assault! Their master plan now becomes clear: to invade each planet in the solar system and make sure that it is inhabited exclusively by chickens! The time has now come to don your non-stick egg-repulsing helmet and make the biggest omelette you've ever made as you continue your adventure in the second chapter of Chicken Invaders: The Next Wave. Only you can make a difference. 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?
