Factorio Forums

So I have been playing through free play on peaceful and have a found an issue. The game states that science pack four requires alien artifacts but to my knowledge these can only be received by killing aliens. I would like to see an electric mine that excavates for alien artifacts so that they can be mined. Perhaps this could be made that they have a higher mine rate in peaceful.

This is currently not possible in vanilla, but there is a mod for that (in fact it adds alien ore that can be mined by regular drills, and transformed into alien artifacts). Alternatively, it is planned that alien artifacts will not be used any more for research in 0.15 (next major version of Factorio).

I'm sure there are mods, that have some source of alien artifacts other than aliens.
