CIU version 140


This update replaces the “Ultimate Omelette” episode with the full “Revenge of the Yolk” episode in CIU, directly playable from your Profile screen. This is a temporary and experimental feature, so enjoy it while you can, and report bugs here.

Also, Christmas content has been added to mobile versions of the game. It will be automatically activated about 3 weeks before Christmas, or you can manually enable it now through Options → Seasonal Content.

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).


You will lose:

  • any mid-mission progress
  • your language selection
  • your seasonal content setting

BUG: When hosting a multiplayer room, the host spawns with the firepower upgrade he purchased before, while others spawn with the normal 0

Are you talking about CI3 specifically? This is expected. Players joining on “Prologue” will have Ion Blaster lv.0, because I can only pick a single default weapon for the entire mission.


Yeah but the host spawns with lv.10… is that normal??

Yes. That’s how the Prologue works in CI3 for single-player.


Oh alright, so that means that in multiplayer, everyone should have lv10 at the start or only the host?

Usually, callsigns use the same usual text font, but I’ve never seen this kind of text font for a callsign in CIU. Is it normal?


Does can add sound scream of boss chicken in CIU when it starts attack?

Yeah, they must be using a different kind of alphanumeric characters using Unicode.

Which boss?

Regular/normal boss chicken

alr in the original ci3
don’t you remember?

@InterAction_studios You might have missed me a medal, can you try giving it again?

Finally a new CIU topic because I have a question for IA.

Do you ever plan to return to making linux native version? Wine/Proton works fine, but just asking.
For some time now, linux steam marketshare passed few important points.
These are the stats for October 2023.
Zrzut ekranu z 2023-11-25 12-31-45

As you can see Linux (whole) is more than Windows 7 and Windows 8 combined. And Also Linux (whole) is more than MacOS (whole). Now, we don’t have MacOS version of CIU on Steam, but it probably could come there?
