Chicken Invaders 4: Ultimate 

Save the earth from the 120 waves of invading chickens set on conquering the planet. Kill all the chickens, collect weapons or shields and stay away from eggs or other projectiles.

Earth is under attack by chickens from outer space trying to punish humans for oppressing and eating earthling chickens. This is the fourth installment of the Chicken Invaders saga. Now the chickens are angrier and more dangerous.

Despite the attractive and well-narrated story, this is little more than another shooting game like many on the market. What differentiates it from others is its tongue-in-cheek approach. Unlike other shooters that are more dark and "serious", this one is fun and colorful. Instead of destroying human or humanoid enemies, you need to shoot flying chickens that will throw egg bombs at you. The mother ships where they come from are, of course, hens that also are armed. The graphics are very vivid and are supported by matching sounds, which are also fun. Imagine hearing clucking sounds instead of explosions. All this make the game even funnier.

The complete pack has the full game, as well as Christmas and Easter editions. It has also an important discount that you can get in the developer's webstore. If you like shooting games and want to get a laugh while playing, you may want to try this one.
