Xenonauts: Community Edition - changelog and downloads

Recommended Posts

NOTE: This post is no longer maintained. For the most recent release, downloads and changelogs, see the Release Announcements sub-forum.

The latest stable version of Xenonauts: Community Edition is version 0.34.2.

Below is a list of older X:CE releases.

Version 0.31


See the release announcement for details.

Version 0.30


See the release announcement for details.

Version 0.28


See the release announcement for details.

Version 0.27:


Changes related to LOS:

  • Implemented true 3D LOS algorithm. Cases such as a soldier standing on the roof in the middle of it seeing an alien on the ground level right next to the building's wall should no longer be possible.
  • Fixed LOS problems in night missions, such as showing tiles that were too far to be seen in darkness, while still not showing aliens on them.
  • Alien alerts should be properly added/removed depending on what aliens are visible.
  • A tile is considered visible only if its central cell is visible. This mostly prevents seeing enemies if they are almost completely obscured by a wall, such as if right behind a corner.
  • Improve looking past a corner. If a soldier is standing right behind a corner and looking diagonally past it, the soldier will be able to see much better past the corner (the LOS will be equal to area where shooting is possible because of leaning). This and the previous item may result in a character standing behind a corner being able to see enemies further past the corner, while the opposite not being true (in older releases this was often the other way around, making standing next to corners actually a disadvantage).
  • Re-enable cover indicators present in older beta versions and improve them to show blocks by walls. This should show for any tile all directions that are covered. Note that this does not show the quality of the each cover, only directions. Configurable by ShowCoverState in config.xml .
  • Use leaning even when targetting a tile (previously leaning worked only when targetting a character).
  • Show properly why a leaning shot is still blocked.
  • Removed visibility range bonus for being on higher levels as it was fundamentally broken. May be possibly re-added properly later.
  • Debugging of LOS. Pressing 'H' and 'G' in GC editor will control various modes showing LOS (the most useful is "LOS cells", "visible tiles" is also useful, the rest are mostly internal).
  • Make walls temporarily transparent also when they obscure cursor position.
  • The roof-toggle button now has a 3rd state that also hides walls and props on the current level.


  • Berserk will work as intended when caused by low morale panic - the berserking unit may now fire around randomly, not necessarily targeting a particular unit.
  • Mind control now affects the unit for 2 turns, but with a delay. Immediately after MC, the mind-controlled soldier just stands around with 0 TUs, the next turn, the soldier is fully available for the aliens to use.

Modular system:

  • Load sounds from mod directories.
  • Buttons and bitmaps in Lua files now load images and sounds from mods properly.
  • Fix installing of mod .zip files that do not explicitly include subdirectories (e.g. Armoured Assault).
  • Allow MODMERGE matching for XML files that use element content as key (e.g. cities.xml).
  • Allow replacing text when merging XML spreadsheets using MODMERGEREPLACE.
  • Reworked starting soldier loadouts to be better, added new role (Specialist).
  • Added flags for all soldiers, including the preorder ones.
  • Log notifications about airplanes status changes allowing to be operational again.
  • Added animation for soldier melee attack (based on grenade throw, so does not entirely fit, but better than no animation).
  • Fix scrollbar sometimes getting out of sync (most noticeable in the Barracks view).


  • Soldiers with destroyed corpses can no longer survive.
  • Stunned soldiers keep bleeding and may bleed out.
  • Avoid crash when enabling/disabling weapons in air combat when the fighter has no target selected.
  • Fleeing shouldn't be stopped by TU reserve or spotting a new enemy.
  • Recognize alien grenades as grenades (makes their image show in quickthrow slot properly).
  • Prevent possibility of getting stuck in a prop after running up stairs into unrevealed part of map.
  • Low morale berserking no longer always tries to target a character.
  • Do not add a bloodstain when a character falls unconscious.
  • Fix a (LOS) hole in Cruiser's hull.
  • Offer few selected hardcoded windowed resolutions in the launcher.
  • Fixed mission_researches for some any-UFO setups

And the most significant change for modders in 0.25 is that it includes a functional version of llunak's modular loading system, for which there be separate documentation, but the current thread is here. Modders should try and make as much use of it as possible so that mods do not conflict!

The Download Instructions are a little vague to me.

Got this OK

Or Download 0.26HF1

(More information here)

Link is 0.26HF2 ?

X:CE 0.26HF: Attachment 5098

Leads to this
Invalid Attachment specified. If you followed a valid link …
Is this v0.27 ? Links broken if it is.

X:CE settings mod : Attachment 5091

xcesettings.zip is same as the v0.26 page so not v0.
27 ?

GOG Site provides

Xenonauts v1.05
and only
Xenonauts v1.09 Patch

A problem if v1.08 is required.

Getting a valid X:CE v0.27 would help though I think

X:CE 0.26HF: Attachment 5098

is meant to be X:CE v0.27 making it clear would help and if it isn't X:CE v0.27 where is it

Totally Confusing me this one, it may be obvious, but naming X:CE v0.27 download link as X:CE v0.27 would be so much easier to understand.

I never expect Modding to be simple but I don't recall finding the mods download being so hard, even if the broken link worked, unless it's file name is XCE v0.27 I would be still unsure I had the right files.

That won't be anything to do with X:CE. Light drones cause a lot of suppression which damages soldier's morale. In conjunction with a soldier dying, it's quite probable that your soldier's morale was depleted sufficiently that they panicked. It won't show on their morale bars, though, because when they panic they recover a large amount of morale to stop soldiers being panic-locked over multiple turns. So it looks like the panicked for no reason

yep,but all of them were 2 majors (one died) 2 captains,2 lt and 2 sgt....only 1 sgt didn,t panic and his lost of 10 points of morale is show....I've never seen such situation before in my game and they are not rookies but guys with 10 or more missions. Bravery between 50 (one of them) to 79. And guy with 79 just flee after death of my major (he is captain) and second guy who was near to him didn't flee (sgt with 62 bravery). All of this 2 didn't recieve surpression fire from drones - only saw alien.

i know, but as i said before in playing my soldiers were many times under fire from drones and surpression was and losing of time units and morale was also....but never happened situations like this. One of two with low bravery was fleeing but rest of them even under heavy fire was able to use half of TU to change possition, withdraw and get the morale that has been lost.

i have removed 0.27 and install 0.26 hf2. I couldn't load save from mission when this strange situations happened becouse i have CTD when I was try to load. So I use another save before ground combat and send on the same crash site exactly the same team. And now I am playing this mission in 0.26hf2 and You know what I see??? My soldiers have another bravery! And I am talking about the same soldiers that went so much panic in this mission playing on 0.27.....any clues???

I'm not sure what you mean. Do you mean they had different bravery scores to what they'd had previously?

I suspect this is due to morale increases that you get for killing aliens. These bonuses temporarily raise your soldier's maximum morale. It might not be this, but I suspect this will be the explanation.

ok, I removed XCE 0.26 from launcher menu and install 0.27 instead of automatic overwrite and after playing the same mission - when I had more deaths in a team - it seems to be fine - no more such panic and flee even when my man takes damage and was bleeding while aliens still shooting at them. So maybe there was a problem - in automatic instalation and overwritting files?And I must say that Your work on LOS is great! No more strange situations when player can't make shot from corners and as I see even in a close area to Charlie there is no "stupid" blocking in LOF....good work!

no, I have notice morale bonus after killing alien when my men had 99+. I can't explain this but really when i start the same mission with the same team I have notice a different morale in 0.26hf2 and 0.27 (the bravery level looks the same). And I'm playing on Ironman so i haven't got many saves (only 2 sometimes as backup) and I can't go back and try some issues playing in different versions.

ahhh, by the way kabill......just getting myself better in playing Your sky mod :) ..... I am able now to take corvette with 2 fighters only using 2 foxtrots

Sounds like you're better at it than I am!, now! Foxtrots are certainly queen. I'm hoping that will be less true when I get round to a revision.
