my "squad" didn't seem to realize they were being attacked?
What do you mean? They didn't react? Didn't throw/fire weapons?
They don't react in any way to being attacked. They keep throwing spears or firing arrows or drop rocks etc. until they die.
I have never seen them not do this. It's impossible for them not to. If a dino is onscreen and at their level, they will attack; if not they stop and wait. They don't run away or anything like that. They're not supposed to.
I've updated the Pandora version a few times since this release, but there seems to be a distinct lack of interest in a pc version, so it'll remain as a Pandora exclusive for now.
