All acid weapons causing damage to armor (before this armor is counted).
As for lobstermen, they have 90% resistance to acid, so yes, spawners and toxiguns almost completely useless against them.
Ha! One of the most armored thing in the game is resistant to the anti-armor tech. Boo.
I did manage to clear it up, after something like eight hours of save puzzling, mostly with the Squeezers and Thermal Tazers.
Alas, no Examination Room. I'm beginning to think something is bugged here. Base (non-open) XCOM:TFTP
didn't even have the exam room as a proper object, since it was subject to its own bug. But, here, the Exam Room is the only path towards Advanced Bionics, according to the research tree. And it's just plain missing everywhere. None in alien dungeons, artifact levels, not even a carefully full-cleared alien base.
I mean, surely, mostly anything you need to get past mid-game bottlenecks would be in an alien base, right?
Where is this supposed to actually appear? Am I running into
this bug? I can hack it in the my save file (STR_EXAMINATION_ROOM) and research it, but I can't find it in-game.
