Invincible characters

In Deus Ex, "invincible" describes an attribute of certain non-player characters that renders them invulnerable to any damage, whether from the player or other non-player characters. Many characters are invincible presumably for story-related reasons. In such cases, invincibility prevents story-essential characters from being killed by the player. Some characters that are initially invincible can be killed later on as the story progresses.

The "invincible" attribute (bInvincible) can be set for characters via console commands.
