Chicken Invaders

Chicken Invaders is a series of arcade-like game that parody Space Invaders. They were developed by InterAction Studios.

Chicken Invaders
Chicken Invaders has a simple gameplay, with one or two player capability. The levels consist of ten waves. The waves never differ, keeping in the same order wave after wave, but they do increase in difficulty. In all the waves, eggs drop from the top, which have to be dodged, and gifts need to be collected to receive points. The player's weapon has 8 power levels, and missiles can also be collected.

Chicken Invaders 2: The Next Wave
Chicken Invaders 2 has one or two player capability. It has 110 waves (including 10 secret ones), ten each in each of the 10 levels across 11 systems. In all levels, except in the Asteroid belt, the ninth wave has a bonus (usually a new weapon, or extra firepower) if no missiles are used in the level; in the asteroid belt, there is no bonus, only a continued onslaught of asteroids. The last wave has a boss in all systems except in the Asteroid belt. Weapons have 10 levels, and a secret 11th level, which can only be reached by collecting an additional 10 powerups after the 10th level powerup. In all the waves, eggs are laid by the chickens (Christmas ornaments in the Christmas edition), which have to be dodged, and drumsticks need to be collected to get missiles (holly leaves in the Christmas edition).

Chicken Invaders 3: Revenge of the Yolk
Chicken Invaders 3 is similar to the second edition (with up to 4 player cooperative play). It has 120 waves, in 10 levels across 12 systems in the galaxy. There are 30 unique bonuses. Weapons have 11 power levels, and a secret 12th level, which can only be reached by acquiring an additional 10 powerups after the 10th level powerup (the 20th). Plus, there 8 unlockables you get at the end of completing the game again and again(indicated in the last cut scene).

Reception
CNET gave 4 out of 5 stars to the first Chicken Invaders, highlighting the humour, graphics and sound but criticising the lack of any features for customizing the gameplay. CNET also awarded The Next Wave 4 stars, again commending the graphics but criticising the lack of a windowed mode. The Next Wave was rated "mediocre" by GameSpot, criticising the repetitive gameplay and indistinct enemy bullets. However, the colorful, cartoony graphics where highlighted, as were "flashes of understanding of what makes a good shooter".
