Fallout ( Unofficial Revised Ed.)
Protectron are much like sentry bots in line of defensive and offensive capabilities. Unfortunately they are a far earlier model then the sentry bot, and therefor are far bulkier and less efficiant. Protectrons recieve an innate DT/DR of 3/30%, like the robo-brain, however they can move through any terrain humans can, at less of a speed. Where it takes 4 AP for a normal human to mvoe through difficult terrain, like a cliffside, a protectron can maneuver the same area at a cost of 8 AP per meter moved. Protectrons also recieve either Repair, Energy Weapons, or Science as a TAG skill.
