Full Release 7.18.4 STABLE Released!

[Chris]

We've released the 7.18.4 hotfix patch onto the main branches for everyone, as we didn't get any major new bugs during its time on the Experimental branch. However, if you're tyring to mod the game, you'll probably want to to switch to the Experimental branch as the newest hotfix 7.18.5. contains some additional fixes that address some issues with mod loading in the current version!

PLEASE NOTE THIS PATCH IS NOT AVAILABLE ON GOG - the upload to GOG failed, and it's quite awkward to try and re-upload it. The next hotfix (7.18.5) is already out on GOG's Experimental branch and will probably be released to everyone in the next 24-48 hours, so we're just going to leave it as is because GOG will be back in sync with Steam when that happens.

Changes:

• A number of players were upset that the 1.0 launch removed the ability to mod the .json game data templates, as these had been moved inside Unity asset bundles for performance reasons. The game now contains a .zip file called "all_templates.zip" in "Xenonauts2/Assets/Assets/xenonauts/" that contains all these templates, and modders can just unzip them to return to the previous setup (as the game will always look for a file on the file system before checking inside the asset bundles). 
  • Be aware that unzipping all these templates negates all of the performance increase that came from putting the files into asset bundles, so you should only unzip the files if you are actively working on a mod!

Bugfixes:

• Fixed a crash that could occur when swapping between soldiers in the tactical inventory.
• Fixed a crash that could occur when a file for a new language was added but not all data was present.
• Fixed an issue that could cause the game to save over existing saves if you created a new campaign using the same name as an existing campaign.
• Fixed the buttons on the Mod Manager screen all displaying the same text.
• Fixed the Mod Manager "Developer Mode" checkbox not working.
• Fixed the game permitting 7 Geoscape bases rather than 6.

I'm playing 7.18.4 STABLE. There's no alien research projects: no autopsies, no interrogations. Not even in xenopedia. The game ignores that I've captured the corpses of Sectons, mantises, symbiotes, and even a living mantis.
There are only automatic autopsies and interrogations of the Cleaners. What's the problem? What should I do?

Welcome to the forum.  That sounds frustrating.

 

• Open the game & load back into your campaign that is having a problem.
• Hit "F11" to bring up the bug report menu. Click the first option to export a bug report zip
  • The bug report zip file will be saved into My Documents/My Games/Xenonauts 2/BugReports
  • it will be named something like bug_report_2026-04-05-09h01_gc_7.18.4_user_f11_0.zip
• Create a new post in the bug report subforum https://www.goldhawkinteractive.com/forums/index.php?/forum/33-xenonauts-2-bug-reports/
  • when you are writing the post, drag and drop the bug report zip file to attach it to your post

The bug report zip contains your save games, game logs, information about your hardware etc, it'll make it much easier for the developers to understand what the issue is.

 

 

edit:  Have you completed the alien biology research project?   That's a foundational research project that needs to be completed first for many of the alien research projects.

Yeah, I think this is the problem. The alien autopsies are only available after completing Xenobiology and Waveform Analysis might be required for that.
