I did a search on this just now and came up with nothing that specific. Just descriptions of what artifacts do and what not.
However, my problem is, I have no idea how to collect them to begin with. Im playing a big 1 v 1 game with my brother and theres hundreds of planets and several stars. We have rules set so we cannot actually kill eachothers home planet, etc, so the game is dozens of hours long. Anyways, throughout this game ive done alot of "Exploring" of planets, and then the guy is like "They've discovered an artifact on your planet!" (the in-game voice that talks to you). And I go to the planet and read what it does, but then I look at my "Artifacts" list in my UI and still all blank. I look around the planet that found it and highlight all the buttons but cannot find anything about actually collecting this artifact into my list of artifacts. They're all just blank still stating I've not discovered any yet. But im positive I found an artifact because the planets Notifications list on the far left of the lower UI bar when the planet is selected shows that they discovered an artifact on that planet.
So what gives? maybe im looking at them the wrong way, please help!
