Comparison Topic: The Evolution of Chicken Invaders

A few notes before you begin reading:

  • Yes, this topic is parallel to my Universe vs. The Episodes topic, which you can check out here: Comparison Topic: Universe vs. The Episodes
  • This is NOT me hating on Chicken Invaders, this comparison is just done for fun
  • The information is based off of the latest release of each game, so it’s subject to change in future versions
  • This will regularly be updated as time goes on
  • Yes, I did most (if not, all) of the research on the CI Wiki, most of the credit goes to @EmeraldPlay and the other users for the information
  • Most elements of Universe will NOT be listed on this topic, only a few crucial parts, a more in-depth comparison is linked above
  • This is still very WIP, so bear with it for now :man_shrugging:

So, if you remember my other topic, Universe vs. The Episodes (linked above), I compared Chicken Invaders Universe to the episodes, so I have decided to build a similar topic to compare each of the individual Chicken Invaders games. Just like the other topic, multiple areas will be covered.

Anyway, let us begin!


DIFFICULTY

CHICKEN INVADERS 1

  • There are no difficulties/skills, instead the game gets harder as the player progresses

THE NEXT WAVE

  • There are only two difficulties, Rookie and Veteran
  • Difficulties are selected in the options menu

REVENGE OF THE YOLK AND UP

  • Difficulties are selected on the mission screen, and cannot be changed once a mission is started
  • There are three difficulties: Rookie, Veteran and Superstar Hero
  • Superstar Hero needs to be unlocked before it can be used, in CI3 players need to complete the game in Veteran (although chances of getting it are random), and in CI4 and beyond they can buy it for not more than 40 keys

UNIVERSE

  • Difficulties are now called Skills
  • They now define the health of the enemies rather than weapon damage
  • Three new Skills were added: Tourist, Seasoned, and Virtuoso
  • They must be bought before they can be used
  • And when you do have them, you have to mount them before starting a mission!
  • Rookie is still the default
  • Missions have a difficulty value, which affects how hard it’ll be

GAMEPLAY

DOS VERSION

  • Similar to the DX Version, but there were no missiles, no food collecting, and no weapon upgrading

CHICKEN INVADERS 1

  • Players can only move left and right, so they’re stuck at the bottom of the screen
  • No touchscreen, joypad or mouse support

THE NEXT WAVE

  • Players can move freely in any direction
  • Mouse control was added on the initial version

REVENGE OF THE YOLK

  • Players can overheat
  • Joypad support was added

ULTIMATE OMELETTE

  • The camera can zoom out, for larger bosses
  • Players can rotate (a good example being the Gyroscope Malfunction wave)
  • This was one of the first Chicken Invaders games to have touchscreen support, added on a later update
  • Satellites were introduced

CLUCK OF THE DARK SIDE

  • Turning affects object gravity
  • Other than that, not a lot of stuff was changed

UNIVERSE

  • Extra lives and superweapons can no longer be obtained in-game, they must be mounted prior to the stage
  • The behavior from CI1 (stuck to the bottom) is present, but reserved for the Anniversary and Squawk Block mission types
  • Prior to EA v3, weight affected the player’s movement in the mission. Something similar to this behavior is, however, still present with the Heavy Bomber spaceships

WAVES AND MISSIONS

DOS VERSION

  • Only four waves, three classic invasions and a boss
  • The Java version only had a Classic Invasion
  • No, neither version lasted forever like the DX version, instead you got stuck on an empty space after the last wave ended

CHICKEN INVADERS 1

  • The same 10 waves are repeated through the entire game
  • Chickens with 360º animations were featured on “The Invasion Begins!”, “Be Quick or Be Dead!”, and “CrossHatch”
  • This game lasts forever, well, until it crashes

THE NEXT WAVE

  • Waves are more diverse, examples include “Scramble! Breakfast time” “Paratroopers!” and “Berserk Chickens”
  • However, that specific wave type was repeated three times through the chapter! (there were exceptions, in those cases a “Be Quick or Be Dead” wave was added in between)
  • New enemies, like the Parachute Chickens and the large eggs were added
  • 360º chickens have blue vests in the Remastered version, and the opening cutscene of both revisions
  • “Be Quick or Be Dead” was redesigned, but “The Invasion Begins!” and “CrossHatch” were removed
  • The three asteroid waves were condensed into one single encounter per chapter
  • There are 110 waves
  • Asteroid missions were introduced

REVENGE OF THE YOLK

  • Enemy movement is more advanced, allowing for more complex waves, like “Chicken Geometry” and “Bonus Challenge!”
  • 360º chickens were removed, possibly because of the amount of sprites they needed
  • New enemies like Rogue Missiles and Egg Drones were added
  • Only “Classic Invasion”, “Terminator Chickens” (slightly redesigned), and “Asteroids” returned from the previous game
  • This game has 121 waves, with one being sorted as the “Prologue”, guess who?
  • The Asteroids mission type returned, but Comet Chases were also introduced

ULTIMATE OMELETTE

  • Camera changes allow for more dynamic movement on each wave, like “Three-Ring Circus”
  • Chicks were introduced
  • No waves returned from the previous game
  • Only 120 waves were featured
  • New mission types were introduced, these were: Feather Fields, Droid Raid, Retro, and Supernova

CLUCK OF THE DARK SIDE

  • Planetary missions were added
  • Not much has changed other than that

UNIVERSE

  • Missions are shorter, limited to 40 waves
  • Weekly Challenges, however, last 100
  • The Anniversary mission lasts 120, like the episodes
  • The Heavy Bomber test flight lasts 50
  • Most of the mission types from the episodes were reintroduced (Those being: Supernova, Comet Chase, Retro, Droid Raid, and of course, the Chicken Invasions)
  • Squawk Block, Boss Rush and Darkness mission types were added
  • Waves from all previous games will return, alongside new ones to come soon
  • Planetary missions aren’t present, yet
  • Neither are the Feather Fields

BOSSFIGHTS

CHICKEN INVADERS 1

Big%20Chicken%20(CI1)

  • Only one boss, the Big Chicken (pictured above)
  • Just like the rest of the enemies, this boss got harder as the game progressed, to the point of reaching a boss named “Big Chicken #214748363” (unofficial term, coined by the fandom, but more specifically by @EmeraldPlay), which had NEGATIVE health, making it invincible!

THE NEXT WAVE

  • Three bosses were present, the Big Chicken, Military Chicken, and Mother-Hen Ship, but each is fought multiple times
  • Starting from this game, the Big Chicken #214748363 bug (negative health) no longer appears (might need confirmation for this)

REVENGE OF THE YOLK

  • There is more variety in the bosses than the previous game, like the Mysterious Ship and the UCOs

ULTIMATE OMELETTE AND UP

  • Camera controls allowed for more complex and larger bosses, like the Super-Chick, or the bosses of the Planetary missions of Chicken Invaders 5

UNIVERSE

  • All bosses from the previous games have returned, with the exception of CI2 bosses
  • New bosses were added: Henlley’s Comet, Bossa Nova, Magnetic Manipulator, and Master Squawker

  • This game introduced the “Weapons Rush” unlockable, that allows for all weapons to spawn from the first wave, instead of per chapter.

CLUCK OF THE DARK SIDE

  • The Hypergun, Corn Shotgun and Riddler were introduced
  • The default weapon became the Hypergun
  • The Weapons Rush unlockable was retained

UNIVERSE

  • Weapons Rush was removed, as the weapon unlocking system has been revamped
  • Weapons are unlocked by tiers
  • The default weapon is the Moron Railgun, also a new weapon
  • Players are, however, not limited to this weapon, as they can purchase weapons from the store to set them as their default

  • As of Early Access 36, the first ever charging-based weapon was introduced: The Absolver Beam

Don’t be offended, but some things are rather simplistic:
“Waves are more diverse”, “There are more bosses”, “Higher detailed models”

Yeah, I need to change that

don’t forget this rather small detail of the music change, how ci2 was a chiptune music and then in ci3 it all gone fully orchestra
