Fallout 3 creatures

==General information==
When in the proximity of others, all Fallout 3 creatures will fight each other as long as they are not part of the same faction as grouped below. For example, deathclaws will attack mirelurks, but feral ghouls will not attack glowing ghouls. Deathclaws and mirelurks are not affected by the Animal Friend perk, as they are both considered abominations. Feral ghouls will be friendly to a character with the ghoul mask equipped.
