This location can be confusing for some. So I made a few videos and included some tips and tricks here.

Here is everything contained in this first guide:

00:00 Video start.

00:44 – 02:15 Tools that I used to get through the location and tips for what you should build.

03:52 – 04:20 How to reach the portal after having already been to the location at least once.

04:31 – 05:25 How to reach the cafeteria. 05:25 – 07:48 Cafeteria walkthrough.

07:48 – 16:37 is where I hit the underside area and fight the new Rats.

16:37 – 23:37 How to tackle the next area featuring the three separate walkways and how to find the large elevator to continue through the location.

At this point in the game, you should really have the personal teleporter built. Also, make sure that you bring a bed with you if your character gets tired easily. I don’t bring coffee because of the inventory space.

Here is everything included in part 2:

00:00 Video start 00:00 – 01:49 Entering the next major area.

01:49 – 04: 51 Completing the first shortcut loop.

04:51 – 06:01 Reaching the first bridge, and no, not the one with the tank at the end of it.

06:01 – 06:46 Unlocking the elevator shortcut.

07:22 – 10:09 Unlocking the first major door.

10:09 – 21:51 Going through the library and getting ready to tackle the major bridge.

This is the video that shows you how to get through the bridge with the mounted machine gun. Here is what’s included in part 3:

00:00 Video Start
00:00 – 01:44 Prepping for the bridge with the tank and mounted machine gun at the end. If you didn’t watch part 1, I always suggest bringing mugnades. HOWEVER, there are grenades under the bridge that you can use as well.
01:44 – 04:25 Breaking the mounted machine gun and pressing on to the Sun Disk.
4:25 – 19:28 Exploring the rest of the location before reaching the Sun Disk in the final part.

Finally, this is how you reach the Sun Disk:
