"Mars Awake" achievement? How do I get it?

[Corfaisus]

Do I have to get tier 5 on all zones or is there something I'm missing? I'd like to at least get one ending for all my hard work.

Have you made it to the Helm and spoken to the Sentients?

Where is that on the map?

You know that one chamber where the side of the lower Core is exposed? There's a crack in it near the top of the chamber. Crawl into that.

Now for some reason the game won't even fire up on my computer. I got a new graphics card, but I doubt that'd prevent it from functioning.
