Extremely lost, as usual...

[Salty Sis' 4U]

I have issues navigating, a lack of mapping or points making this all the more tricky. Right now I'm stuck in the Nucleus, Utopia Classifieds. Killed all the enemies here, virus-ed up the missile and I've blown the fuse through the mesh and down the elevator... But the door the fuse opens up, according to the wiki after an hour or two of aimless confusion, hasn't shown up. Or I'm somehow missing it. Anyone able to help?

Advice? Video or pics to show where to go?
Anything?

[Salty Sis' 4U]

Damned Nucleus. This is insanely frustrating.
WHERE IS THIS SUPPOSED DOOR!?
IS IT JUST NOT OPENING!?

The way to the final boss is all the way on level 1 at the end of the long bridge. To open that way up you have to take an elevator from level 2 to 3 and there you pass a tram to drop down to an area with 3 nanite blobs. There's some console there, you'll know you've found the right one because above it is a monitor that shows the level 1 nanite obstruction.

I'm in Utopia Preparation Classifieds. Floor 2?
Floor 3...?

Do you mean past the mesh on this floor and down to the fuse? I blew that thing already. Killed literally everything. Can't find any way out now aside from Launchpad 2 with all the nanites, or back through the security door on the lower floor into the gas.
Which is a dead end.

[Salty Sis' 4U]

I've seen no tram.

[Salty Sis' 4U]

Jumping off of the nanite ledge in Launchpad 2 is death no matter how I leap, I always respawn right back at the entry of this room to boot.

[Salty Sis' 4U]

I'm lost AND trapped in this hell.

Level 1. When you first enter nucleus you cross a long bridge then go left because the middle is obstructed by a nanite wall. If that is still there, you have not found level 3. Level 3 is only reachable by a normal elevator. When you take this elevator you will come to a location with a med refill station, a tram, and a hole to drop down in.

[Salty Sis' 4U]

Dropping down the hole by the fuse in the lowermost floor is also death, but it sends me back to Ops.
Not sure if that's good or if I'm losing out on something and will end up walking all the way back.

[Salty Sis' 4U]

Well. Need to find another friggin' fuse to rid myself of that wall, huh?
Fug. I wish there were a navigation impant.

[Gorwel]

To give you a rough idea how to find this elevator, when you exit the medbay from level 2, turn right, then turn right again. Following this path you will reach a hallway with toxic sludge on the floor, at the end of this hallway somewhere should be a room with a nanite blob, behind this blob is a blown out wall. Through this blown out wall is another hallway and at the end of this hallway is the elevator and a door opening a shortcut.

[Gorwel]

If you found the spot where you upload the virus, then you've been to the room with the blown out wall behind the nanite blob. Not the same room, but it's on the path to the virus room.

[Salty Sis' 4U]

I can get up to a spot where it LOOKs like I should be able to raise the Ops station...
But it's just a tad too low down and I can't find a console for it.

[Salty Sis' 4U]

At the end of the slimy hall was a door that opens up to the stairs. The stairs lead up to floor 3... Where I was before, if I'm not mistaken.

[Gorwel]

Don't worry about raising the Ops, level 3 is extremely small. Once you get there and use the console you have to go back to level 1 and you won't need Ops anymore.

On Level 3, there's a total of 3 nanite blobs. Two overcharge pipes. You want the overcharge pipe that's in the room with only 1 blob. There's stairs behind the blob leading to it.

And you haven't reached level 3 if you haven't taken elevator or seen a tram.
