Introduction

There are 20 artifacts that you will need to collect in order to obtain the achievement “A Sharp Mind”. The first one is part of the story, but the rest you will need to find roaming around. I chose to do this after completing the story, and would just start shifts that were in the daytime. Turn off Callout Options in the RB menu. If you happen to have a crime happen near you, just ignore it.

Note: You will gain a new ability upon hitting Police Officer Rank 16. It is called Artifact Detector. You can turn this on in the Callout Options (it is not set by default). It will help you know you’re close with a flashing icon by your mini map, as well as a beeping sound.

IMPORTANT: Please be aware that the collectibles are listed as I personally found them. Each area doesn’t contain a specific artifact. Instead, it just counts up from 1 to 20. Luckily, once you have obtained one, there will be a green check on the location so you know not to look again. The only reason I named them was so that you could follow along while you scrolled down.

The map saves the ones you’ve completed, so if you don’t need a detailed explanation, you can just see the maps completed below. If you’d like more assistance, you can keep following.
