Things you may not have noticed (spoilers ahoy!)

[AurosAerondo]

A bit late to post, but, on my playthru. this part seriously kills a part of the story. Don't know to put this on bug or things you may not notice.

Spoiler below!

At the end of the tunnel where ARK was transferred from Tau to Phi, where you met the wreckage and corpse of Neil Tsiolkovsky, there is a way to go thru the wreckage above the corpse by taking a long steel and rotate it so it made a diagonal way for you to jump over. beyond you will find yourself under the tunnel. (Don't know how you just suddenly fall down here). you could either crouch all the way under the tunnel for quite faraway and met up with a dead end, or there is a way out here where you will be in the large area (which is the area you are being chased by the giant gulper which hasn't occur yet.) If you go to site Alpha from here, all the chat between Simon and Ross will be skipped and you will be skipped to the cutscene where Ross is being eaten alive by the gulper. And you will never know what happened, what did Ross want you to do, What is the monstrosity in the middle of Alpha, etc

Luckily there are lots of LPs where I could get a grip on what happened there
