SOMA Enemies, Post-Release

[LordOfDragons]

Well if he sees you the first time he will never ever loose you again. Its impossible to escape.

And yes i think he isnt a human. I think he is a squid that is WAU infected. Think of it: The terminal at the beginning of TAU. Anglerfish, Whale and Squid.
Anglerfish gets anglerfish... Whale is the Leviathan and the Squid is tentacle guy.

I've never seen a squid in a diving suit ._.

I think everything kinda points to Yoshida since he was last using the suit. WAU made him change like it did with the other creatures.
They used the squid to attract one of the WAU creatures in the deep sea for experiments i think. At least the part at TAU where you arrive with the elevator shows it.

He is really difficult to hide from for me. But the area doesn't have too many hiding spots, so i literally had to run all the way back towards the exit to find one (And of course he knew which room i was in).
