This list could not have been compiled without the help of Cosmic Schwung, who figured out all of the locations and put them together from various incomplete guides and walk throughs. There was not one place we could find where all locations had been documented.

This list was orginally put together on the Steam forum in this thread and added as a community guide to make it easier to find.

The locations are in chronological order.

After jumping over the pistons inside the factory and defeating the pyro, shuffle along the ledge to the right of the doorway. The artifact is at the end of that room.

After rotating the crane (RC-325), climb on to it and continue left. Jump the gap and go to the very end of the crane arm to find your second artifact.

This area begins with grappling outside the factory. Upon reaching to the third platform, double jump to the right. This hidden area of platforms leads to an artifact.

This one is hidden at the water puzzle. After bringing the stone block up to the second story using the turnstile and lift, move the block to the far right corner. Use the box to jump up to the ledge.

As soon as you begin the log ride, head backwards. After clearing a few rafts you will find the artifact on the last one.

At the spot where you first encounter the possessed jungle beetles, head over to the rock wall on the right. Jump up to the top and you will find an artifact inside an abandoned cave.

This one is immediately after the orb challenge. Before climbing the vine, head left and there is a moveable block in the wall. Drag it aside to find your seventh artifact.

After defeating the demon priests at the courtyard you must go left with the grapple hook. Head toward the rope bridge. About halfway there, there is an opening on the right with an artifact.

After gliding across some rock platforms you land at a cliff with a rope bridge behind you (immediately before the Chieftain Hammerhead battle). The bridge has sections missing, but can still be crossed. At the far end are four spirits guarding the artifact.

After blocking all of the boulders and fully extending the bridge, head right. Instead of going down the bridge, make a leap of faith off the right side. Double jump and glide and you will land on a platform with the artifact.

Just beyond the worm-infested swamp is a platforming section. Once you reach the second platform look to the opposite side of the ravine and you will see some vines on the left. Double jump and glide over then climb up to the ledge.

After killing the pyro turn around then go to left under the stone archway.
