Early Access version 124


Party like it’s 2002! “Chicken Invaders: The Next Wave” (a.k.a. Chicken Invaders 2) was released on 22 December 2002.To commemorate the 20th anniversary of that occasion, CIU supports a special mode which simulates an (approximately) authentic 2002 experience: graphics have been reduced in color and resolution, music has been replaced with era-appropriate tracks, and certain special effects have been disabled.

CIU v.124 always starts off in this mode, but it can be disabled through the main menu (you must restart the game to enable it again). Also, for technical reasons, this mode is not available on Android.

Admittedly, this mode comes a bit earlier than expected, because there are three main events in December and unfortunately they all come very close together:

  • “Chicken Invaders Universe” leaving Early Access on December 15th
  • “Chicken Invaders: The Next Wave” 20th anniversary on December 22nd
  • Christmas Edition on December 25th

Some of these events clash together (e.g. music replacements from 20th anniversary and Christmas), so I’ve decided to spread them out a bit so that they don’t overlap. Starting with the next version, 2002 party mode will still be available, but it will not be the default startup mode (because not everyone is familiar with Chicken Invaders history, and it would not be appropriate to leave Early Access with 20-year-old look as default).

Finally, this version re-enables cross-platform multiplayer (Windows vs Android), which had been temporarily disabled until a crashing bug could be fixed. This was one of the most elusive bugs and it took almost two weeks to track down, because… compilers.

Bug/Idea medals will be awarded later in the day. Note that your medal cannot be awarded if your in-game callsign doesn’t match your forum name (put it in your forum profile where it says “name” so I can find it).

  • :bulb: Clucker Bombs no longer cause area damage when fired inside an enemy (impact damage remains) (@EmeraldBirb :medal_sports: Idea)


Not a nitpick, but one of the stage transitions bits is pretty long, long enough that it “conflicts” with the theme when starting the next stage.

On the upside, the chiptune music when starting the game is a instant classic.


Explain button:


report bug momento

I suppose in “pro-gamer” mode it would be. Will look into it.

Fixed in v.125 :medal_sports: Bug


Also this?

Dark beyblade lmao


Suggestion: Make the satelite/primary fire/special weapon (and even pause?) disappear when the spacecraft is near it like the scoreboard or the timer bar

(in this case i’m hiding at the special weapon button)

Quick info: If you still have the “-2002test” command entered in the Steam game launcher, the 2002 mode will boot up when you open the game.

Tell me you don’t read patch notes without telling me you don’t read patch notes

It turns out that special mode is not available to me at all? Because I can only play the mobile version due to the fact that I simply don’t have a computer in principle

set fps to 30 for extra 2002

These “borderline” just pop up on my screen. Is this intentional?

This doesn’t reference any keyboard/mouse controls.

Will consider it.

They are visible to the host before they fly the mission, so it’s not a problem if joining players see them too

There is already a callsign “LaserLite” in the game. Is that not your account?

Update: I’ve awarded it to “TidePopper” now. Log out/in to receive it.

I have no idea what this border is… it seems to be rounded on the left side but not the right? What? :eyes:


for some reason i met this ( in 2002 Edition )
Where’s the rocket icon?


Yes laser lite is my account but its my old one.
