Food is a game mechanic used in the Chicken Invaders franchise since Chicken Invaders (DX Version). It also existed in the DOS version, but it wasn't collectible. Food, when collected, will give you a certain amount of points and food units, depending on the variant collected. When you collect 50 food units in Revenge of the Yolk, Ultimate Omelette and Cluck of the Dark Side, (100 with one of the Scoring unlockables), or 25 in the first two games, you gain a Missile, and the food counter resets to zero. In the flashversions, they're used as a way to get extra lives. There, you obtain them every 100 food units collected. In Universe, they no longer let you obtain Missiles, but they can be instead sold at Space Burger stores in exchange for Keys.
Most common type of food, appearing in all Chicken Invaders games. Gives 1 food unit and 200 points (in Chicken Invaders (DX Version)), 250 points (in The Next Wave), or 100 points (in the games following it). In Chicken Invaders (DOS Version), it's purely cosmetic, as it can't be collected.
Four variants of it exist, and they don't differ in the amount of points/food units they give. Those variants are:
Introduced in The Next Wave, this food item drops less often. Gives 10 food units (12 in The Next Wave before version 2.30), which is the highest amount you can get from the food items. In the game it debuted in, it gave the Appetite bonus. In its sequels, it gives 1000 points. It has two variants, and those are:
Regular (every edition/game it appeared in other than The Next Wave Christmas)
Mistletoe (The Next Wave Christmas)
Uncommon, exclusive to Chicks. Gives 3 food units and 100 points. Introduced in Ultimate Omelette.
