Early Access version 12


Another content-oriented update (but with a lot of bug fixes and small improvements as well).

Customization options (paintjobs) have been added to the H&C series. New wave types have been added. Squawk Block missions now have a boss. Retro missions have been added. And there’s a new frozen planet environment for missions flown on “Frozen wasteland” planets.

In the mission listing/selection screen (and in your favourites), you’ll now be able to tell which missions you have flown/completed/failed.

Community credits go out to @cook1ee for his Wave Insight idea, and to @RoboCat for the frozen environment look. Congratulations, recruits! As usual, there are :medal_military: medals and :key: key rewards on the way (“when they’re done”).


This update is mostly backwards-compatible, but you will lose:

  • any in-mission progress
  • any menu options you have configured


  • Added “Droid Highway” wave to Droid Raids.
  • Keyboard hint only shows “left” and “right” keys for Squawk Block missions.
  • Added “Lethal Connections” wave.
  • Fixed typo in “Rookie” skill description.
  • H&C series: Added paintjob customization options (6x fuselage, 4x wing, 3x pods, 4x canards).
  • Added boss at end of Squawk Block missions.
  • Changed “Game Over” message to “Mission Failed”.
  • Remastered “Treble Trouble” waves from CI3 (both horizontal/vertical variations).
  • Remastered “Chicken Geometry” wave from CI3.
  • Added Retro missions.
  • Multiplicity boss: Reduced Infinichick health by 50%.
  • Multiplicity boss: Increased Superchick health by 33%.
  • Added last/best result to mission info.
  • Improved mission color-coding.
  • Fixed incorrect placement of player projectiles due to a camera mismatch between client/server when continuing a mission.
  • Fixed typos in Insight descriptions.
  • Added “Waves Insight” (based on Madam Madámmes new prediction technology)
  • Added “Frozen” mission environment (based on What should the mission look like on the planets "Frozen wasteland").
  • Exchange rate from food to keys is now doubled (from 0.035 to 0.070).
  • Stars’ “core temperature” reduced by a factor of 10.
  • Skills can now be purchased only once.
  • Skills now sorted by difficulty (instead of alphabetically).


You are reminded that during Early Access you are responsible for backing up your own progress. Make a copy of everything under C:\ProgramData\InterAction studios\CIU (including all sub-folders).


NIce.Good Job InterAction Studios.

Hopes about retro background

It is there.


I didnt see any new link. EDIT: Its there

Has the default color for the H&C engines changed? All of my H&C spacecraft had their inner engine color changed to white. The outer engine color is also off.

Also, there’s a typo here - “Frontlet wing”.

Thank you :+1:

Argh! This is a problem in the upgrading code… taking server down to fix this. It will take about 20-30 minutes. Server is working again.

Fixed typo (for next update).

Gameplay of Retro mission

Oh good!
Thank you!

So I tried the new update, I’d like these changes to be made if possible:

  • Make the screen freeze way quicker on frozen planets, now it’s too easy to melt the ice
  • Please add blizzard effect to frozen planets to make it even harder to see

How can I find Retro mission???

Black holes.

You have to find a wormhole and orbit it. Only wormholes have retro missions.

It’s so hard!!!
Show me the picture!

Also why don’t retro missions have their music from CI4? Please bring it back it was the best theme ever.


About Squawk Block: I surprised, you created new boss for this mission
