I'd expect it to work on humans, but not aliens (or civilians). Am I wrong?
Yes it works, and vanilla medikit always did too
It works on both stunned aliens and not stunned ones (and civilians too). If they get tranquilized (their stun goes higher than health) they will go unconcious on the end of x-com turn or after being hit by any sort of weapon. Large units are not affected at all.
I also wanted this to drain energy but that was too glitchy.
Here are the graphic files I use (made by me, based on awesome civilian medkit graphics).
I was simply stating that as of now, healing won't work for either aliens or civilians. And the civilians part is sorta wrong...
I can heal aliens in my build of the game. Since i play with bleeding aliens enabled that is quite essential to keep them alive till the end of the mission. No bugs have been observed, they are treated just like x-com units.
It's not bad if you use alien bleeding mod. You may heal an stunned and wounded alien ... but in any event, an alien which awakes is inoffensive because it is unable to collect a weapon (exept Chryssalid of course ).
And psi-aliens. And if you dont want spend time catching those awakened aliens across the map
