Pros:
Funny, attractive, imaginative aren't enough to depict this game. The sound effect is very mysterious to lure players to look into what happened, and the plot is unique. Should we decide to be vegetarians or vegans?
Cons:
There are some crashes among chat tools, desktop tools when playing this game. You have to quit for avoiding the crashes.
Story:
Attention, chicken lovers! Alien chickens are coming to take revenge on human beings, since we haven't stopped eating chickens! The invaders are attempting to invade the solar system now, who is the next hero to save whole solar system (including eleven planets and Earth)?
Will you challenge and beat these invaders?

Tips:
The game leaves us a bullet rocket and some bonuses. Level 1 is a get-familiar-with-this-game mode, which provides one alien chicken for players to practice. Therefore, you could soon get in the role with less worry.
At first time, I controlled the mouse not to get drumsticks (chickens' legs) as well as eggs, as I considered them dangerous; however, my hypothesis was wrong - eggs and omelettes are dangerous yet drumsticks are very useful for the rocket!
If lucky, you could even upgrade your weapon - a certain chicken would hide the gift, just shoot them.
One level is nothing but avoid the flying rocks or asteroid shower. Don't crash them, or you will lose a life. You could utilize the arrow keys to avoid them - up and down arrow keys move the rocket forward and backward.
Fun Factor:
Chicken Invaders 2 is successfully popular and carries on the former style. The replay ability of this game lies in its degrees and easy-to-operate modes. The designers are smart to lead players to soon get on well with it.
Eggs are laying in different angles, then, how to avoid them becomes a sleight. Many players share their skills; if you need help, just search them online and you won't be disappointed.
Remember, you are not only fighting with cuckoo Chickens (another name of these alien chickens), you are also on the solar system; to avoid flying rocks is important as well.
Conclusion:
This game fits all ages. It's a nice recommendation for families to enjoy fun. Enjoy it now!
