SPOILERS -- things that change on the maps

That Ross.. conveniently following me so I'm the one to deal with the surprises and monsters. I find it strange Catherine didn't seem to care when you tell her about killing the WAU, she's only interested in her Ark.

Overall the monsters in SOMA are more varied but they are easier to evade than Amnesia's ones.

Construct it seems to be killing someone behind the door, or is it just lashing out ? After all it only just recently woke up just after you.

Yeah, Catherine and Ross never seem to interact AT ALL, she doesn't seem to be aware of him or the true extent of the WAU. It's possible that Catherine's ARK obsession is a result of her limited capacity as a cortex chip, that's also a fanwank theory (please tell me if that word is banned here) I have about why Simon does not react to certain horrifying sights and scenes like you would expect a person like him to.

Regarding that last sentence, that's part of a cut character from the game. That headless corpse you find was not a 'murder victim' of the Construct, it was supposed to be another WAU creation similar to Simon, but incapacitated and traumatised, possibly due to it's recent encounter with the Construct. The voice files are still in the games data folders. This is why Simon does not react to it in any way.
