|The following is based on Fallout: Brotherhood of Steel 2 and has not been confirmed by canon sources.|
Texas Rattlers are mutant snakes in Texas.
These giant rattlesnakes are all bark and no bite. Weighing in at 500 pounds and starting almost six feet tall when upright, this critter can really ruin a man's day. The good news? The radiation and growth has diluted their poison. Now you'll only get sick if one bites you, instead of ending up stone cold dead. Of course, they don't really even need that poison. Not with gigantic fangs about six inches long...
Texas Rattlers were to appear in the canceled Fallout: Brotherhood of Steel 2.
