Can someone tell me where are all the artifacts and what does it do cause I'm new and how to get all question in NOAH
If you talk to Khannonkhan and Credence, they will give you hints about the item's locations, there is one per level and several are obtained through natural progression.
There are 6 questions with NOAH, here's how to get them (spoilers if you want to find them yourself).
1. Read NOAH's user manual, you have a stat roll, so you might have to do this a couple of times. You will know if you got it if the text says you got the gist.
2. Watch a Western.
3. Play NOAH in a fighting game, this is another stat roll so you may have to try multiple times, you will know if you got it if you win the game.
4. Play an erotic game, obey twice, then disobey.
5. Do the erotic section of the Holodeck.
6. Follow the glitches in the Home Section of the Holodeck, then go visit him in the containment bay and talk.
Hope this helps!
