I believe I was clear that this does require the Retribution Expansion.   Please be more specific as far as what you're looking for.  As far as if it will work with the base game - no DLC's, no other expansions other than Retribution, that I don't know.  But it only taps in on the Retribution files.  Would require further testing for the specifics.

Edit: Does appear to work in vanilla game with just the Retribution Expansion installed.

A1:  The Preumbral Beacon Artifact - Summons a creature from space, does work.

A2:  The nano Fabricator Artifact -  Boosts the construction on a selected world.  I believe provides a boost of 25% construction value to the selected world, not 25 points.  So early in the game, I agree it would be weaker, however, later in the game or on a higher construction world this would be much much more powerful than 25, 50, or 100 points.  This one will get stronger as the game goes on versus The Precursor Library Artifact that looses it's value as the game goes on (see A4).  I'll double check on this though.  Double checked it is just 25 points as you stated.  I'm doing an actual play through right now I'll see if I think it should be adjusted.

A3:  The Dimensional Mirror Artifact - Reveals a portion of the galaxy.  I agree it may be good to expand this a little bit.  I'll look into this as I further test the impacts of the mod.

A4:  The Precursor Library Artifact - Instantly complete the current research, may seem overpowered at the beginning of the game or on a small map, however, later in the game as your civilization get's more research power this becomes less and less powerful.

@PocusFr - I have revisited the NanoFabricator. At this point I have adjusted it to provide 50 points instead of the standard 25 points.  Other changes in 1.02 is the Betatron Collider only causes 10% damage instead of the default of 25% as to me this seems too cheap of a move to destroy an entire fleet by deploying this 4 times.  Now one needs to deploy 10 times to destroy it.  

Also included a fix for Prometheus Stone as there is at least one artifact that depends on Prometheus Stone and in the current build nothing produces Prometheus Stone.  This corrects it so Prometheus Stone is again produced by the Prometheus Stone Mines.

Question to others, The Precursor Temple Artifact still seems overpowered to me.  I may cut it back further to only 1,000 influence points.  I'm looking for additional feedback on this.

Thanks.
