After you go through it you will get to the alien language encoded door. To the left of the door (when you are facing it) is the alien artifact.
Once you get past the Red marker area …
… you will get to a locked door.
Turn left of it and you will see the artefact glowing in the dark.
Standing next to the artifact and looking back you can clearly see the door.
Alien Artifact 07
You will get to an area you climb to with a cargo lift and where you have to turn these huge alien things to get them to align and to turn on the machine. As soon as you disembark from the cargo lift you will get to a T junction and going left will get you to an oversized tentacle blocking the way. Behind the tentacle is the artifact. Go the other way around to reach it.
Taking the cargo lift will get you to this area.
As you leave the lift you can see this tentacle/alien growth to the left.
You can;t see it from here but the artifact is on the other side.
Go around and you can see the artifact shining behind the tentacle (also the cargo lift is in view to the left).
After you go through it you will get to the alien language encoded door. To the left of the door (when you are facing it) is the alien artifact.
