|The following is based on information from Fallout: Brotherhood of Steel 2 and is not canon.|
These molerats are meaner than ever, and ten times as ugly. Standing over three feet at the shoulder and weighing in at around at 200 pounds these critters are fierce and dangerous. The only good news is that their eyesight is poor in the daylight. You just don't want to meet one in a dark, dark cave.
Giant naked molerats were to appear in the canceled Fallout: Brotherhood of Steel 2.
