I've heard of some companions not leveling with the Courier, and being killed as a result. But every time my companions are beaten senseless, they end up merely unconscious.
Can companions die? If so, under what circumstances? Is this a "hardcore mode" thing?
Yes it's a hardcore feature, your companions CAN die to the enemies. There are various other ways that companions can die. They can be killed while they are not your companions. So, before getting them, or after dismissing them.
There are also some reports that companions can be killed in casual mode by doing massive damage to their bodies when they are knocked down. This is probably a bug.
I know they can die in both hardcore and casual. Hardcore being from anything and casual being from massive damage which only the courier can deal that much in such little time.
Yes, they die on Hardcore, and I don't know whether it's possible to bring them back or whether you just have to replace them.
Yes, they can die, but only by your hands.
Your companions can die, but not of enemies. If the Courier attacks his companion, he will die.
