This is the 2020 mod I was talking about: https://github.com/neagix/faf-necro

Thank you for the replies.
BTW, I tried the necro mod from 2020 on github, because the 2014 mod does not work properly with FAF at all. It seems to integrate perfectly with FAF, the icon was there, I could build it, and the unit moved fine. Unfortunately, it only had assist, capture, and reclaim buttons, and no the reclaim worked just like the engineer reclaim, so it looks like this mod was never finished, which explains why I haven't seen it released.

@Jip It gives each faction a resurrection bot, similar to Total Annihilation. I saw someone was working on an updated version in 2020, and there are some files on github, but I don't see that it was released?

I searched but got no results.
Is there a version of this mod that works with FAF available?
