Protectrons are those fellas you find encased in storage tubes that you can activate with a specific role. They are a bit clunky looking and incredibly slow (something you should be thankful for). If they are in medic mode, they’re only able to damage you if you stand right next to them, since they use an electrical arm attack. Police mode is much more dangerous, allowing them to shoot constant laser blasts from each hand.
The best advice against these guys is to not destroy their arms. If you do, it will trigger the self-destruct sequence (indicated by the body becoming red hot and glowing). At this point, the Protectron will try to charge at you. Take it out quickly or suffer an explosive death. If you happen to be at a safe distance, though, feel free to take out the arms since you’ll have ample time to destroy the bot before it gets close.
Other than the whole self-destruct issue, stick to shotguns, armor piercing rounds, and energy weapons. These will make short work of these poor clunky beings.
