Last update: 11 May 2016
After the second detonation a cutscene starts - you'll fall down, retrieving Codex on the way. Head forwards in the complex room, until you get attacked by a large Necromorph.
After getting to the fork, walk over the catwalk to the right. You'll find yourself in front of the alien gate. You can open it using the previously learned code.
Audio Logs 1/3 - On the table in the left part of the fork - you have to bypass the system to restore the power.
Side mission [Artifacts Storage] - Go to the left on the fork and bypass the system to activate the elevator. The side mission starts there.
In the next room you'll find the generator - when you start it, plates in the on the floor will be activated. Thanks to them you can enter the zero-gravity state. Navigation in this room is quite difficult, so try to occasionally rely on locator to head to the correct side - mainly up.
Upgrade Circuits 8/10 - It floats in the air.
Finally you'll reach another door - a code is written on the wall.
You'll get to the path blocked by large blocks. Stand on the round platform to strengthen kinesis effect and use it to remove the blockade.
Upgrade Circuits 9/10 - On the scaffolding near the platform.
